It's not about what it can hold, but what your fuel system can support and truly it can't support 17psi of stock turbo cfm. You could've very well damaged something and not even know it. Wastegate line popping off+CA18DET+stock fuel system= Cracked ringlands and or melted pistons (You're over the limit).

That is exactly how I finised off my CA before I rebuilt it. Competely stock CA (except for FMIC) at whatever the turbo maxes out at, toasted my rings and caused something to score the #3 cylnder and piston.

You might want to check your compression. The way to do it is listed in the FAQ.

Yea mine came off somehow or another, but it blew my intercooler piping off before it reached any high boost.
