Eh, mine went 13.0 bone ass stock with the paper filter. Others have dipped into the 12's bone stock.Originally Posted by SLOWR/T
Never seen one go faster than 13.5 stock. Seen modded ones go slower but the owners could drive for ****. Its ok though cause at the end of the day you own a RWD Grand AM
Of course, I picked up almost 40 rwhp from intake / exhaust / tune... so theres a big bottleneck right there.
