I took the car into KPM where I got the flash tuner. Spoke to Dave there he said just run it on the 8 pound tune the car was makin a few too many ponies for the stock valve springs and bouncing. Runs like a dream on 8psi. Gettin full 3.5" system turbo back, 60 Lb injectors, nizpro valvesprings and tune in a fortnight so should be runnin 12 psi after that. sweet
