Whats the highest boost everyone has hit on the stock turbo? The other day I noticed I hit 35psi on my pillar gauges and dash gauges. Never hit that high before.

 

I've maxed my 35psi gauge a few times before. Once you're up into that range you're really not making any more power with more boost, it's getting past it's efficiency range and just pushing hot air at that point. I know I've heard of a few guys with stock turbos and 190cc injectors push them up to the low/mid 40's.
