Sorry, I know I'm a newbie. Just picked up a 1990 ZR1 with following mods.
Billy Boat exhaust, Marc Haibeck chip, aftermarket intake (k&n?) Anyway - car pulls strong to 5500 and then seems to fall off? Is this typical? Or is it just my imagination. What are the optimal shift points for peak acceleration. Thanks sorry if this is a dumb question.... |
