Just had new motor put in my 98 GT. has 1300 miles on it. I sprayed it for the 2nd time now it don't want to pull well. Seems to to still have all gears in tranny but won't pull like it should. Motor sounds strong and just purrrrs. Could it be the rearend? it has a stack rearend. Please let me know what you think it might be.
all help would be thankful....

 

Gonna need ALOT more details... what exactly is it doing?

 

1). Do you have a tune for spray? What Size Shot
2). What exactly do you experience that leads you to believe there is a problem?
3). Have you checked your plugs to see if there is anything abnormal with them?

As mentioned above, more info plz.

 

maybe you need a tune on the new engine?? probably sprayed too much for the stock computer

 

Yeah it has a tune. when it spayed it tryed to take off but it just rev'd up and stop pulling. The plugs looked great the car was running and pulling great til the spay hit. It has 125 shot (wet)on a forged internals, PI swap, bored 0.20 over and 2200 took off the deck. stock cams in the PI's. compression is 11-1. But ever since i sparyed a wheel chair can out run it lol... But like I said before the motor still runs strong just no pull from the drive train side ( rearend or trans. just don't know which) It also has a stage 2 race clucth. from Zoom. Thamks once again guys but more helped needed.

 

Maybe there is something wrong with the nitrous solenoid and its just dumping fuel???

 

Well I got my car back to the shop. The problem was when I spayed It broke the clutch disk. (stage 2 Zoom) the clutch was rated for only 350 hp and when I sparyed it broke the disk. so now I am going with a centerfield duel frection. should have it back friday.
thanks for all the help you guys offered. I was very thankful.

 

man, that was confusing as hell! all you had to say was the motor revs but the car doesn't go
