just havent seen or gained any benefits to running that high of boost. 32 +/- a few is plenty sufficent.
while my motor was being built and before i built the trans i dynoed my lbz with just a airdog2 200 and robs max effort tune on bone stock everything including trans and intake even it dynoed 529 and i hit 31psi max. would spike to 33 then settle back down to 31.
