I too used to think it didn't have to go, remember our last conversation 
Javad? What did you find out?

I for one have found out (on the 3B motor with stock motronic, bigger 
injectors, RS2 turbo, EM and intercooler) that it can do 365 HP at 5600 
RPMs and as much as 420 lb/ft of torque at 3540 RPM running 1.7 Bar 
(relative) peak boost and dropping to 1.1 at 7k. No ignition issues so far 
with this car, though on another 3B I've put my hands into, with the same 
stuff except for a K26/27 turbo, we've had some ignition misfires (sounds 
scary) around 5.5k RPM running 1.7 Bar at those RPMs. I guess the turbo was 
pushing a bit too much air into the cylinders and has possibly blown a 
spark away...???

Mihnea, tuning happily in Belgium and around Europe (sig line à la Hap 
Maguire) :-)
