Let me preface this by saying I've been doing a lot of reading and I know this is a loaded question due to the amount of variables involved. Supporting mods in my profile should be up to date. Boost leak tested up to 25 psi (I was aiming to run 20 psi). Stock 7 bolt long block compression test: 180 175 180 175 (was performed yesterday), so the engine is healthy.
After doing some mods this past winter and firing up the car to tune it, I have been getting the well documented issue of boost creep. I pulled the turbo, ported the 90 degree turn down, waste gate hole, wastegate exit, and entrance into my down pipe. Slapped the turbo back on the car and while it creeps less, I am still creeping up to 24 psi (24.4 psi max from my ECMLink log). In terms of knock, I am getting ~1 count of knock during a 3rd gear WOT pull, so that is not an issue. I also have not started tuning as I am trying to resolve my boost pressure first.
Bottom line, I believe the stock 7 bolt on stock head studs should be able to handle 24 psi out of a small 16g. Should I tune around my creep? I know that the small 16g is out of its efficiency range at 24 psi, will the turbo fail on me?
