Very strange, those numbers should be MUCH higher.

Have you changed your trans fluid? maybe the trans is starting to slip up a bit and you're getting more drive train loss? same for the rear diff?

 

rear diff was done at 60k trans at 45. ive got 70k on now. he ran it 1st through 4th flat out on the dyno and he said it wasnt slipping at all.


Remember this is the 3.5 not the 3.7 motor so numbers are going to be lower.

My Stillen Gen 3 comes in tomorrow. hopefully i will be able to get it on pretty quick and go retest and tune.
