Right I've been tearing my hair out for a long long time now over this and would welcome some advice...
I have a Leon Cupra (early model so APP and K03) and went for a Stage 1 remap. Once it was applied to the car, I immediately thought that bottom end torque had increased as it felt a lot more brutal low end, but the power felt standard at the top end once 4000 RPM was hit.
Puzzled, I got hold of Will at P-Torque and explained to him and he invited me along for a diagnosis and a dyno test. On the dynos, the bottom end torque was up but peak power hit 176bhp so basically no difference to standard. He also did some VAG-COM logging and said that timing was 10 degrees out and it wasn't boosting as much... although he may be able to clarify if he remembers this.
I got back onto the guys who remapped the car and he came down the very next morning F.O.C from Leicester and spent a couple of hours trying to find a problem. He noticed the standard DV is sticking open slightly, so we replaced this with a Forge 007P but this didn't make much difference. He swapped the MAF for a new one - no difference. He cleaned the throttle body out - no difference. He did an N75 bypass - no difference. He did some other bypass with piping (can't remember exactly) and it pulled much stronger but still "tailed off".
Whilst this was going on we did some VAG COM logging which revealed massive boost drops at the top end where the flat spot was. The boost curve went up up up then a HUGE dip to 0 and then straight up again... In the end I got the car put back to standard and I'm in the process of getting a refund.
To help rule out whether or not the map would be at fault, I got hold of Badger 5 and went down there for a free Revo trial which really blew me away power wise but still wasn't quite as good as it should be...signifying an underlying problem with the car.
So off I went to a VW garage and had a full diagnosis which returned nothing but the temp sender being faulty ( I knew this already - which I've replaced now).
I'm at my wits end as it just seems to be an invisible issue that no one can find .......
I'm not alone as I found someone on another forum having a similar issue with their Mk4 Golf GTI.
Anyway, apologies for the giant post. If anyone could spare any constructive advice... anything at all then I'd be very appreciative.... thanks
