Okay so the other day i took my friend and I on a long straight away too c how fast i could get it and I only could top it at 132mph and that's all i could go it didn't wanna go no more. I have on cheap a$$ tires now and 16inch steel rims. Could the low speed rating tires have anything to do with me not going any faster ? I use to go over 140mph Oh and when ever i do go over 100 sumthing my check engine soon light pops on then after a few days of driving normal it will go away. The light blinked on and off then stayed on after i was going 132 then started to slow down. Dam i need those 1.9 mod rockers. I guess i will hook up my tech 2 and see whats going on.
