Fix the timing first, would probally like 20 inital (wild guess)and 34-36 total, That will help, and your 60ft sucks.....is it spinning? Theres probally a 1/2 second left in your combo with tuning, perhaps more.
Yeah, the rear end is really stiff and I need to get to the track and muck around with it more. It was spinning the boots. It was my fault as I was doing mega burnouts with the Drag Radials.
