Thanked 5,021 Times in 4,072 Postsi used to run 20.8psi from mine, but the turbo is well out of its efficient boost levels running that high. 15-16psi is about as good as you can expect from it

Thanked 2,777 Times in 1,607 Postsi would go for 18psi for longivity of turbo and other bits, but upto 20-21 acceptable, or just push the right foot pedal a little harder :-)

Thanked 342 Times in 293 PostsI would change the turbo for a more efficient item if you want high boost numbers. They are really inefficient when out of their respective efficiency island if you take a look at their compressor efficiency maps. Really much beyond 18psi is not worth it from a 15g even with extensive cooling mods and WI.
