Hi there guys hope some of you can help me work out what is going on with my car as its low on power during its current on going Stage 2+ Remap, its a 2007 LEON CUPRA 2.0 TFSI BWJ ENGINE, MANUAL.
Ok so after about 6 months of owning my car I installed a Full turbo back Miltek exhaust system, consisting of large bore downpipe, high flow sports cat, non resonated center section and Remus sports rear silencer.
The next year I had the car remapped by Angel Tuning but had it put on a rolling road @ FMS local to me before and after the remap.
Before the remap the car was tested @ 251.4 bhp / 219 ft-lbf (Exhaust system showing good performance increase)
After the remap the car tested @ 294.6 bhp / 273 ft-lbf
Not sure what map Angle tuning used as im positive they dont design there own.
Anyway I have since fitted the below hardware to the vehicle over the last few years:
Now the car ran fine with these hardware upgrades fitted but obviously not getting the full potential until it has the software side sorted. I also noticed the fuel mixture probably wasn't great as there was alot of farting and popping from the exhaust but I liked that lol. And i out this down to the intercooler and upgrades.
However the weekend before the remap was booked the uprated internals off the fuel pump failed so I had to re-install the standard internals.![[:@]](/forums/styles/seatcupra/oldforumsmileys/furious.gif "Furious [:@]")
I also replaced the coils and plugs.
Now the car went to be remapped last week by the same company that previously did the rolling roads a few years ago FMS, they carried out a rolling road before and after the remap.
However the rolling road before the remap tested @ 310 bhp !!!!!
Now I was surprised by this given the amount of hardware upgrades installed though it would be higher, anyway they then remapped the car and it only tested @ 329 bhp !
So as far as im aware im around 30 bhp short, however how much will running a standard HPFP possibly effect the map and power????
The tuner said to me that the fuelling seemed ok and the mixture was good if not only a touch leaner during boost. But neither of us could see that that would make up for 30 bhp loss. The car runs and drives fine with no obvious problems. Its also run on high Octane V Power or Momentum all the time. I made sure everything including the air filters and MAF were nice and clean before the car went etc and the car also had no fault codes stored on the ecu.
Now Ive only ever installed parts to the car that I have reviewed (mainly via this forum) and have been proven to work properly and advantageous to the cars performance, I realise there are mixed opinions on the induction kit and that the PCV isnt performance related.
Ive spoken to lots of big and small tuning companies including AMD & REVO, pragmatic tuner, awesome and have been told the car is currently what they would class as Stage 2+, they have all given figure of high 300's (370-380) and others have said they would aim for a MINIMUM of 360 bhp given the cars current spec. I have seen lots of people on here with cars of at the same stage if not with less hardware fitted producing much more power than what mine is currently. I appreciate all rolling roads will read differently and some tuners will raise figures to make them look better etc, but I think from the previous runs on this rolling road that its pretty accurate.
Now i went and test drove the car and wasnt super impressed, it was quicker but had some lag and not much low end power around 2k revs. Spoke to the tuner and told him from what ive read and driven it should be much quicker, smoother and at least 360 mark. He still has the car and is going to take another look at the map this week and speak to some specialist he knows. He also mentioned that he had increased the boost pressure by around 5%. However this is over the standard manufacture map not a extra 5% on the old map. Now He had to build the map of the original manufacture map which he copied of the car years ago as the map that Angel Tuning had installed was locked and he couldn't download or copy it so had to overwrite it.
Does anyone have any advice or ideas on what might be going on here, any help much appreciated or any cross references to other cars.
Thanks

- FORGE FRONT MOUNTED TWIN INTERCOOLER
- GFB DV WITH LATEST PISTON DESIGN
- HPFP INTERNALS
- FORGE TWINTAKE FORCED INDUCTION KIT
- REVO PCV DELETE
- CTS TURBO DISCHARGE PIPE
- CTS INTERCOOLER TO THROTTLE BODY PIPE
