guys im completely lost on this one:
got a used engine for my z, from a g37, changed the top manifold just incase they were different but the engine is flawless, i got the southbend stage 4 street kit, and at first it was okay, i baby'd the car, had rev match on and everything. long story short im at 1000 miles, changed the oil and started to drive my car how i usually do
HERES MY ISSUE:
when im at a light and i want to launch, EVEN WITH VDC OFF, sometimes the car barley revs up, its as if the stop light fuse is limiting me as if i were holding the breaks and hitting the gas but i checked in my rear view on traffic cones and the brake lights dont come on?
so my issue is that i have barely any power when i punch it, and whats even odder, i remember my car picking up A LOT faster, sometimes i feel my car how it was before, and sometimes the car kinda lags as if i had a turbo. ALSO when i have the car in gear, in first, and rev it high, the car inches forward and i can tell im burning the clutch because of the smell, but i bled the CMAK cnc eliminator kit 2 times... i dont no what im doing wrong!?! the only thing i can possibly think of :
bad crank shaft position sensor.
battery terminal is shaking around when im punching it because its not tied down
CMAK cnc eliminator kit is bad or i have to bleed it again for the 500th time
