How much boost is safe?
I'm sure it's been asked many, many times but, how much boost can I safely run with these minor upgrades.
Welmeister Chips
3.0 Bar FPR
Shimmed Wastegate
Stock Injectors
Stock Turbo
I do have a aftermarket boost gauge so I'm more accurate than the stock gauge. Right now I'm at 10.5 - 11 Psi I'm think that the Welt chips are mapped to about 15 Psi when using a 3 bar FPR. I was thinking around 14 - 14.5 Psi to be safe?

Most people would consider 15 psi safe as long as your AFR is ok. 15 seems to be the threshold beyond which headgaskets and crankcase pressures can become problematic
