GIAC software
 

Well recently had Jon at AWE-Tuning hook me up with the giac software and I could not be more pleased. I have all the supporting mods a B5 S4 owner could have with the software and the car FLYS. So happy.....if anyone is thinking of "what to" do first or where to spend their next dollar....AWE makes probably the best equipment out there. FullAWE exhaust with hi flow cats (smoggable) S-Flo intake and AWE intercoolers...APR Bi-pipe with R1 diverter valves (another great company for mods)

feel free to pm me about any of this stuff, other than the software ive done everything on my own.
