I have a stock turbo r33 1993 model just recently as a week ago I installed a boost t to try and find the boost cut on the stock ecu in a nutshell just yesterday had a Apexi Power FC installed and tuned on the dyno reading came back with 212kw 280hpish on 9psi and slowly bleeds off after hitting 9psi , (they tuned my car with the boost t still installed, did not uninstall it and then tune it) could the boost bleed be from the boost t or something els. I was thinking about removing the t and just rec connecting the waste gate without a boost t but am afraid it will mess with my tune. Help
ps I am needing information on what modifications I should do to help increase my kw/hp besides a bigger turbo lol,
when I say stock r33 I mean it’s has rejacket coils a tog tdo6, 3”tbe and fronty that’s aboout it will post engine bay pictures
