Slow response during 1st gear...
I have a 02, sc430. Modded with blitz supercharged and straight exhaust all the way..( accept the 2 catalytic converter before the o2 sensor.) but i have slight delay or lag during the first gear. From (rpm) 1k to 4k its delay or lag.(not revving smooth). But when its reach 4k and above, the power just kicks in suddenly. I hope you guys understand what im saying. Sorry for the bad english.
