I got a hypertech chip for any 89, anyone know if these chips raise the rev limiter? i looked all over the hypertech website but they dont tell you a thing.

 

No the only feature they serve is to bump the timing...hope you didn't pay for it! Quite honestly I am not trying to be rude...they really offer no other advantage what so ever...they state the chips correct and maximize the A/F curve...unfortunately that is not the case with the 87-93 ECU cars and I question it in all cases.

 

i had one and didn' t notice any difference. I sold and made so money off it.
