Help!! Remap Horror Story!

I have owned my 04 LCR for just over a year now and had kept it standard apart from a K&N 57i induction kit, it has covered 34k problem free miles. I spotted a tuning company advertising custom remaps for my car to take it up to around 270bhp and decided to go for it, and booked it in.

When i got the car there the tuner plugged his machine into my car to download the standard map and then proceeded to do a power run as a standard car.

When he did the run the car would only produce 130 bhp and wouldn't boost up, but the car had been pulling like a train on the way there and the bonnet hadn't even been up.

The tuner disconnected various sensors etc to try to find the problem but it still wouldn't boost up. We then took it out on the road to see if it was a case of the car being on the rolling road upsetting something, but it was now as flat as a pancake and wouldn't rev past 5500 rpm. Everyone was mystified by it so they called an expert in from the Audi garage with the vagcom software, but this turned up no fault codes and even the expert was baffled by it.

The next thing we tried was to upload a modified map to see if that solved it but it still ran the same. In the end the tuner had to admit defeat and told me to take it into Seat to find out whats wrong. I took it my local tuner who specialises in VAG remaps and is a Revo dealer where it has now been for the last week and they too are mystifed by it.

As you can imagine i'm well pissed off, my car went in with 225bhp and came out with 130bhp, it had previously had no problems whatsoever and now i've had no car at all for the last week while the experts are scratching their heads.

What makes it worse is the warranty ran out the day before so i'm looking like being well out of pocket, more than that though i just want my motor back! I haven't named the tuning company yet as if it isnt their fault i dont want to give them bad publicity, but i feel that when i took my car in it was as excellent as ever, and when it came out it was running crap and looking like its gonna cost me a fortune in investigative work alone.

The only thing that happened between it running properly and going wrong is the downloading machine being plugged into my serial port so i feel it would have to be a freak situation for the two not to be connected. All the sensors on the engine have been checked and they're fine, there are no air leaks and its not the turbo. Does anyone know of this happening to anyone else???

Any help much appreciated!!!

so there's noting outwardly wrong with your car.... just someone *may* not have dyno'd the car well (or set it up wrong)

I dont want to say just yet in case its a freak coincidence and not their fault, but they have done loads of LCR's and they did another guys Audi A4 while i was there and that worked a treat! They also do remaps for the local Seat dealer as an upgrade option.

No they didnt even get a chance to set it up, it just went wrong from the moment they tried to download the standard map onto their machine! Its dog slow now.. ie 110mph flat out, and 1.1 fiesta acceleration! What makes it worse is i cant find anyone else this has happened too!

Not egging you into a witch hunt... but one outwardly "reliable" tuner, may well be renowned for 'talking ****' - once spotted..

anyway

130bhp just isn't going to happen from your car IF it was revved to ~7000rpm... even with limp mode boost

So they must:

1) have revved the car to a much lower rpm
2) set the dyno up like a monkey
3) have no idea


Out of interest - how does the car perform now? - and what about before they meddled?

Like a 1.4?

I was guessing either a fluke coil pack, or spark plug failure (but even a trained monkey could spot that)

or perhaps some airflow restriction like a collapsed cat, or a baby elephant in his airbox

this will make it a damn sight easier to guess if you let us know where you've been though.

Its running like a normally aspirated car basically, it will only boost up to 1.5psi!!!

:lol: Baby elephant.

Surprised nobody's suggested the maf yet as that seems to be the standard answer to everything.

I say its the maf, stuttering to get to 5.5k and wont go past, take the maf out, and run again, if its back to its old self there is your problem.

Have seen this problem in 2 20vt cars, both ibiza mk3 cupras though but the symptoms do sound the same.

The car has been run with all the sensors disconnected, including the MAF but it still wont boost.
