I was thinking "Ka" and "Boom".

You should be fine.

Actually, it sounds like the stock turbo has trouble holding stock boost, so turning it up with a MBC probably won't get much anyway.

I set mine to 16psi and it creeps to 18psi+ on long straights at the track.

It settles back down to 15psi or so as revs increase towards redline.

I should do some DeltaDash logging.

I read somewhere that the stock turbo is about maxed out, though the rest of the engine will hold. To be honest, with how fast it spools, I wouldn't be surprised that it can only push a little bit more.

Those critters are delicous and one makes a meal. Deep-fried, boiled or baked.... tastee..

STI can hold 100psi for bout .1 second. More if less pressure, less if more pressure.....
