Video of my car, down on power...

... I know pretty much what it needs but I can't afford it right now. It really needs a dyno tune, an alternator, and new lifters (#4 intake and #7 intake leak off fast), it could also use some 1.6rr's it only has 1.52's currently.


See that it runs a little rich, dyno says in the 11.5:1 area.




A short run, definitely down on power.



But as you can see/hear the car shifts really crisp for having a ProYank 3600 stall.

i'de say its running bad. My car runs better then that off the spray, my mods are, hotcam, 52mmtb, cai, mac-mids, along with the stock stamped rockers, and no tune. Something is wrong with your car for sure.

Yeah, I don't know what else it could be. The car seemed to be a lot faster the first time it was put together. I put the motor together the first time in my garage, and then with a stock tune in the car still it ran dead even with my buddies 113 car from a roll. Needless to say I am disappointed for now.

I'm pretty sure the converter slowed it down N/A since it's meant for spray, but not enough to make it a dog like that.
