i would NEVER run 1.1 on a boosted car.
i ran 1.1 on 10Psi on my old GTR and it wouldnt rev over 5500rpm the misses wer that bad.
regapped by hand the platniums to .7 and took for a drive and hello 9000rpm gate and fark it got its bucket load of torque. i remember that day as thats the first time i wet myself in that GTR and blew a cooler hose off. on 10psi haha
