Hi,
I got my 2005 Leon Cupra R around 3-weeks ago and been loving it.
It's only done 22k miles now and has Revo Stage 1, Green Panel filter and a Forge 007p DV.
When I got the car it was running fantastic and pulled strongly and really threw me back in my seat.
Over the last week the performance has gone downhill to what I can say only compares to a standard car I have driven only difference being mine has a tad more punch when the turbo kicks in. (and I do mean slight).
Anyway, I toook the car to JKM down in portsmouth who were fantastic and very helpful.
Car had 3-runs on the Dyno and only managed 228.4bhp at best and 230 ftlbs of torque !
(with Revo)
Check with VAG Com, not a single fault code, fueling correctly, was running on Optimax etc.
No logs on Vag-Com suggested boost leaks as the request boost was virtually matched by the actual on the logs.
Only thing it did show was a massive surge of boost at 3800rpm which very very quickly came down. I will post the dyno plot later
Where has my performace gone ?
Any ideas all as JKM were not 100% sure either ?
P.S. It's not the figures on the rollers that worried me it's the drop in performance and belive me it's noticeable, the rollers just showed the power it was making.
