I am flex fuel setup but was capped at 6psi with e85ish blend on stock fuel system.

The caltracs and and a set of king or fox 2.0 w/ my load leveling bags are next on the list not sure how the caltracs will play nice with a car hauler though btw.

Also getting a set of 4.11 gears w/ upgraded axles, w/ converter now so that should help without having to up the boost just yet.

I like your ideas on the cats and y and I'm thinking just working on getting the trucks to launch will be worth a lot without having a ton of expense.

I think so. Charlie has it running pretty damn good right now, so I will prob leave it like that for this summer and then do my 6.2 after I gather the cam, crank, pistons. I really want to get that 9.76 rear back in w/3.73's because that is the most perfect gear with the 6 speed and a 32" tire.

With that in mind is why I chose 18's instead of 20's when I bought my truck. I researched 17 and 18 tire wheel combos on weight and diameter and it was a toss up on weight.

The thing I don't like is not being able to use a 15" wheel without having to screw with the brake calipers.

That was just from a oem ls2 or whatever tire is on there to the terra grappler g2.

I just picked up the newest grappler tire this week for another project, the ridge grappler pretty sweet tire. Not as loud as other trail or mud tires but tread wraps around and looks pretty mean too.
