34 is way out of the efficiency range id say 24-27psi max. the stock s58 turbos can make around 45-46psi but max out at 32-33psi after that they lose efficiency. In testing we found just a 2psi jump from 33 to 35 slowed us down by .5 in 60-130(this was done within a span of 10 minutes only adjusting boost. S55 same boat 27psi with a taper to 21psi is the efficient range but turbo is good for 29-30.

This post is not to bash anyone it’s just a warning to be careful what you ask for. More boost doesn’t = more power all the time
