Weird it's in the owner's manual for my car.

It should be somewhere around 9 or 10 psi I think. It's 9 for my HPT C70.

Re: (adamjjohn203)

so me hitting 10-10.5 ish PSI is good boost and im at about 15-17 ish driving. how about idle? Oh side bar but it never passes 10.5 psi except for 3rd gear it hits about 12-12.5 ish hammered to the ground. but i have done a complete stage 0 with all new vac lines and stuff

Sounds about right.

For me, I hit peak boost doing a 4th or 5th gear pull, where I start low and go up a hill on the freeway. So I start at around 50 mph, at about 2000 RPM. Boost climbs and peaks at 3500 and holds until I'm going too fast.

Wouldn't think it would be much different than an auto T-5...mine is about 17 in drive...doing down a hill and completely letting off of the gas brings it up to 21~22. IPD tuned ECU- Boost peaks at 16~17 PSI
