I have got 330 BHP going thorugh mine with no suspension or brake modifications, in a straight line it is jaw dropping but I would hate to take it round a track! The sweet spot for me would be the power delivery of my car but with better brakes, coilovers, ARB's, anti-lift kit and a quaife. That would be perfect 
Thats exactly right. I really don't think the GTI suspension is upto the job after 240bhp which is why I did all those suspension mods on my car when I had it remapped. Only thing I am waiting for is an LSD and brakes and I'll be done. I could get Stage 2+ but I don't want to push the car to the limit as thats when things start to go wrong.
