oh yeah trust me i know...but 3800 performance programmed their "top swap" setup onto the PCM and it was supposed to be able to run right.......but it didnt...after i realized it was completely messed up and not running right, i took it to a shop and he got it in as soon as he could which was like a week later....it ran pretty good as long as you stayed out of the throttle...also when it wasnt running right, i was lucky enough to not have any engine knock...it was just a messed up situation!!! but its fixed now!! I got a race against a mustang fox body that runs a 13.5 on drag radials but we're doin it on the street...lol i've been told i should be able to take him but i guess we'll see!!
