Help!!
 

just coming out of work and my mate has a leon cupra type r. and i pulled up side by side at the traffic lights waiting to join the motorway and we both went flat out, but the leon kept with me all the way side by side if not a little in front. i have a 2004 wrx and have just fitted a turbo xs top mounted intercooler, dump valve, zero sports induction kit and a cat back 3" exhaust. Surely the impreza would be quicker? does my car need remapping after having this work done? please help?

The leon is 225bhp as standard and only 2 wheel drive. My brother had 1 and he got it chipped and it shot up to 275 bhp on the rollers. So there bloody quick motors anyway mate
