All I know is... my car goes like a stink now! It is soooooo much faster now in
ANY gear. You really have to be careful when you get on the throttle in the lower gears. Even with 255 PS3's!
I think a proper suspension and LSD are in my future.
Btw... one of the BEST things about the flash tune is the way the power builds. Stock the power fell on its face at 5,500 rpms. Now the engine really pulls well up to 7K rpms. MUCH better power above 5K rpms then before.
