Someone reminded me yesterday that if I break an axle shaft, I've got nothing to keep the axle from shooting out with the wheel... I may not be gunning for a 10.999 afterall, I only have 28 spline axles and no c-clip eliminators... I'll have to be a little careful out there until I get that beefed up! Don't want that thing causing alot of damage!

Well guys, I'm more than happy with my first time out in the new setup!!! I love this current setup, only thing I want to change yet is my 3" down pipe, gonna go either 3.5" or 4", it's gotta be holding me back since my turbine exducer is 77.4mm. First pass was street setup with 4" air filter and going through full exhaust on 7-8 psi, I didn't 2step it very hard because it was my first pass and I didn't know how my 2 yr old 30x9 slicks would hook:

Then I took the filter off and opened my cut-out and turned it upto 12 psi and did this:

It actually over boosted in third tho, to 15psi, but thats ok I had the tune setup to pull the timing to 10 degrees and go pig rich after 14 psi because I'm still on stock head bolts and gaskets LOL First gear never went over 11 psi and second was 12-13 psi. I gotta find a way to fix my boost creep!!!
