my ls it @ 7200...dont over rev ur motor..btw d series has a different base map...everything is diff even down to the fuel..just tune your ecu..but your car is stock so gains are minimal..good luck.
its not like ima be hittin 7400k everyday. i dont drive like dat, i chill most of the time, but then theres that time where u want to let it loose if u know what i mean. ive heard of people hittin 8000k with a stock ls,
i took it off. i dont know why but i coulnt pass 5500rpm's. ma friend told me he did it wit his OBD-2 ls and it worked fine. mine was running like crap.
