what was the compression before ? , 10/11ish seams to be the happy #s now a days,
That's why I went to a taller gear. Stopped a lot of the tire spinning.Took the 05 for a drive. (Left my phone at work). Have to put some weight in the back of the truck or some new traction bars. Serious SRT10 22" tire spin now.
Have to be careful that this thing doesn't get away from me now.
