How much boost
 

I don't lay my foot into it to often but the other day I did and I noticed that my boost during 1st, 2nd & 3rd gear was ~15-18 psi.

What should a stock turbo with a stock wastegate put out?

With your quadzilla having the boost fooler you should be able to knock 30plus psi pretty easy I think.

i'd start looking for boots that are off or leaking.

Boots are OK and I thought the XZT+ just changed the timing.

Went for a quick drive, acceleration feels real good. Going on the onramp, before hitting the freeway and I am over 80 without a problem. With a little power braking tires will spin. If it could go up to 30psi of boast this truck would haul a#$. Are you sure about 30 psi?

with my EZ i can get 21-22 psi i imagine you should be close to that if not more because the XZT+ does fueling also without tapping the wire so it can't be that much fuel...
