Twin turbo boost levels at higher elevation

[TROJAN366]

It is crazy how the different trucks and combos produce different numbers. Even with triples I barely saw 80psi on boost and when I was twinned with this exact combo I saw 65-68psi iirc.

I just wish everything was cut and dry haha I changed the cam and dropped compression along with more extensive porting and my boost number never moved.

what do you mean "you ran some numbers"? is the 26psi what you saw on a gauge or did you somehow mathematically figure it out (dont see how that can be done)

Read that on the guage

Sounds like you have a boost leak..have you tried putting shop air to it and check for leaks?

Kyle I had no idea you made this much boost. My setup peaks around 75psi and I thought I was pushing it.

Could be a gauge difference. I am 16.5:1, stick heads, 3388AF, 120% Inj, 2 healthy stock pumps

I haven't, what's the best way to do that?
