ok with my mods that i have below i am only getting 14.2 psi of boost. i already checked for belt slip and i dont have any. when i hit 14.2 it was at the top of 2nd gear at 7000 rpm. this seems really low for the 2.8 pulley that i have with the ott stage 1 kit. what are some other factors that could cause low boost? it runs rich but i dont think that would have anything to do with boost would it? what do you all think?

 

the exhaust work could explain a couple psi

 

is the bypass hanging open? try the boost bypass mod and this will tell u if that is bleeding off some boost then u will have to go from there.

ok well i did the bypass mod. ran it the exact same way as i did with the 14.2 psi run. only difference is that ambient is 10 deg warmer this time. well i got up to 14.5 at the same rpm. so i dont think it is the bypass hanging open. what else could it be?

 

I have heard of this issue being the tune when the bypass mod doesn't fix it.
