T-28 guys. When do you hit max boost? I'm hitting 1.5bar around 4200-4400rpm does that seem right?.

Seems kinda high in the RPM band. I'm thinking I may have a small boost leak or a bad BPV or something. Oh, currently running stock exhaust with a test pipe. Haven't had a chance to put on my brullen yet.

Default true... but I thought the cat would be the most restrictive in the system? ...
Hopefully the turbo will spool up quicker with the brullen exhaust.
