    Ok, I'm back again after a rather mixed year of injury through to success (see another thread those who want to know)

    I have managed to create the first successful stage 3 1.4tsi in the UK, arguably the fastest road legal one in the World. It is well over 300bhp at the moment and the final dyno and performance figures will be seen next year so keep your eyes open

    This tuning guide will give even the most inexperienced person the understanding on tuning this car to be a giant killer. Not only that, it can be done on a budget. Again, all the information given is all correct and is based on all my own experience and the findings of reliable sources.


    PRE TUNING WARNING

    Make sure you have the updated parts highlighted in the first guide. These include the breather modification, injectors, coil packs, spark plugs, water pump and most importantly the pistons. I could not give advice with good conscious to map a car with the old versions a as they are ticking time bombs. Modifications that increase power through improving efficiency like intakes,intercoolers and exhausts would be OK to do and with all three on a stock car I gained 25bhp at the top of the Rev range.The cost vs reward though I would not say is worth it. You need a good remap to make the most out of these modifications.


    REMAPPING: REVO VS APR VS CUSTOM

    Custom

    If you have any desire to go further than stage 2 then I would start with a custom map as there are no company's offering stage 3 maps off the shelf. Not only will it be customised to all your modifications but upgrades will be cheap and they will work with you to get the most out of your car. Most importantly, you need to find a tuner that does their mapping in house. Some get the car mapped remotely over the Internet or sub contract other mappers, problems occur with consistency of work quality and the fact the mapper never even sees the car he is working on.

    AVOID: Shark Performance and AmD who don't do their own maps. Shark damaged a friends car and over stressed another friends turbo. AmD messed my DSG software up by trying to access it without the right security coding and sent it into safe mode which left me with only gears 1,3,5,7. They would not accept responsibility for it at all. My current tuner confirmed they had triggered an anti tamper device.

    GOOD: Jabbasport; heard good things from every one of their customers

    Revo Vs APR

    The good thing about these is they both have alot of experience with this engine.

    Revos early software was brutal and the fastest ever 1/4 mile was done on their stage 1 software. They later detuned their stage 1 after the problem with this engine came to light. Revo blew their piston in their development car working on stage 2+ software which they later found to be the fault of the vw fuelling management code. They re wrote this and along with different plugs cured the problem. People like myself came flocking to them just to get a reliable car.They called it quits with the stage 2 software and pulled all development on this engine. Revo now have employed someone to answer the phone so you can't get through directly to a tuner. If you ask her a question, she refers to a cheat sheet and basically reads off the information on there. Not what it used to be.

    Apr worked on VSRy's hybrid 1.4tsi and unlocked a few secrets regarding torque limits which they managed to bypass. This unlocked so much more performance that Revo hadn't accessed with their mapping. The 1/4mile was then broken by APR's stage 2 software and still stands today due to its mid range grunt. I have always found you can have a good exchange with a technician from Apr and they are really helpful.

    BOTTOM LINE: APR if going up to stage 2, CUSTOM If stage 3
    COST: £400


    INTAKE: FORGE VS ITG VS CUSTOM

    There are only really two off the shelf offerings here... FORGE and ITG.
    There are a few European offerings but not alot of evidence to rely on. Having seen a dyno comparing the ITG to the FORGE, the ITG is far superior. It's actually the one vw racing use. It's called the maxogen induction kit. I use this myself.
    On the ibiza, it takes cold air from a pocket of low pressure behind the headlight.

    I modified the kit by getting 2 silicone hoses and 90 degree bend so it took the air from the grill. I had to cut away alot of the plastic around where the original intake took its air to pull the ducting through. This uses the force of the air hitting the grill at high speeds to assist the air getting through the filter. It will be colder too.

    Although a custom would be better than stock, you need a decent filter like a MAXOGEN filter and a heat shield because of the heat of this engine is so great. So in this case you might aswell go off the shelf and straight for the ITG MAXOGEN induction kit.

    BOTTOM LINE: ITG all the way
    COST:£300-350(for carbon limited edition one. available on demand from ITG)


    EXHAUST: MILLTEK VS SCORPION VS CUSTOM

    For off the shelf both offerings are around the same price, have the same spec pipe and both have a good reputation. The big difference is the location of the catalytic converter. On the MILLTEK it is on the downpipe, on the SCORPION it is after the downpipe underneath the car.This actually makes a huge difference in theory. Your downpipe is where all the gains come forming performance, the rest if the system (cat back) as long as it is of a certain size, then its only worth a couple of horses.
    So the SCORPION is the one to go for because they have essentially increased the length of pipe before the cat (downpipe) and decreased the part that makes little difference(cat back).

    Custom is another option and if you can find yourself a good local exhaust fabricator, you can have your exhaust done for half the price of the off the shelf offerings. size wise you need to go as big as possible on the downpipe which is 3" but due to the sump at the bend underneath the car, you are forced to go down to 2.5" from there till the end I'd the exhaust. Most exhaust fabricators don't do a 2.75 which is what the SCORPION and MILLTEK are so that's the advantage of the off the shelf ones. That is offset though by the fact you can go up to 3" on the down pipe with the custom.
    The beauty with the custom is you can select your silencer so you can have it as loud(no silencer) or as quiet as you want just by telling the fabricator. A 100cell catalytic converter after the downpipe will give you the advantage of the SCORPION too. You will have to extend the lambda probe lead so it has enough length now the cat is further away.

    BOTTOM LINE: Custom will be cheaper and better for what you want. If your goal is stage 2 then go 2.5" all the way and you'll find your turbo will have more pick up than 3" to 2.5". If you plan on going further then go 3" downpipe to 2.5" catback.
    A less restricted exhaust will help the issues with the engine as it will clear exhausts gasses better


    DECAT WARNING.... Tbc

    Nice. Keep in mind you need stronger clutches if you want to have a strong stage 3.
    Over here the strongest stage 2 are about 260bhp and the strong but daily drivers stage 3 around 330bhp.

    The more you tune the car the more problems you're gonna get especially with this small engine, but this applies to most cars.

    Hope you hit the hp you want without any more problems.
    I'm happy with my light stage 3 at the moment but done with it, currently saving for an evo x :D

    Yeap, these are the only available on the market and they seem to be holding more than 500Nm.

    Dead turbo
    Hi looking for help. We recently bought a bocanegra, which was mapped to 210bhp. So I thought it may be useful to buy a miltek turbo back system with sports cat. Which didn't fit as easy or as well as I had hoped.. Had to re route a/c and alt wires to behind the cat. Anyway it's been about 3 weeks and now the turbo has sh** it's self. Does anyone know if this has anything to do with a possible pressure difference on the pcv system or just bad luck? Please help ordering a new turbo and don't want to kill this one :D
    Ps she's on 65000 miles and is a 2011 year. Also brother in law said he noticed blue smoke on start up about 3 weeks ago

    Been a while since this post I know but what turbos and intercoolers are people using for stage 3?

    Does this means getting a revo stage 1 would increase reliability over newest OEM software (which technically addresses fueling issues and stuff)

    Since a lot of new people are asking about the 1.4tsi engine and these threads have loads of useful information, making them sticky. :)

    Hello there everyone i have some questions about my build so i have a 1.4 TSI Cupra made in 2011 and i've been going through this for a while now over and over again but some opinions by you would definitely be helpful , so currently i just added my spring booster and changed my coils to the R8 ones , my car is already running a REVO stage 1 (supposedly) has a check engine light and i'm living in Cyprus so if i'm not mistaken REVO is not really made for my country's heat so hence the fact that i have a check engine light also it doesn't really feel that great and i thought another tune would feel better , so my plan currently is get a Scorpion exhaust cause i feel like that would be the best option for my 1.4 TSI Cupra i've been hearing mixed reviews about the FORGE intake so i feel like i'm going to follow lucifer's advice and go for the ITG ( if i'm able to source it in cyprus which is giving a tough time also for the exhaust ) , and finally because i don't really trust anyone in cyprus to tune my car i'll be getting an APR stage 2 , but for some reason as i said earlier i can't really find anyone that provides that for my car , so i have this other option which is a guy that tunes cars for etuners motorsports he told me he can get me a custom exhaust a forge induction kit and he will make me a custom tune so what's my best bet here?

    If you think heat is an issue then you need an intercooler upgrade, you need a big one.

    Yeah I'll take care of that as soon as possible but still i don't think revo is a good idea in general
