Have a Procharger p1sc on l99 other than that full 3 in exhaust no cat 1 7/8 Texas speed before I put on the headers I had catback exhaust making 6.2 psi at wot since the install of the headers no tune yet I dropped to about 3.2 psi is there a problem somewhere or would a tune help bring that number back up. I know I will lose some boost because I created a less restrective path for the air to travel but it just seems like more psi than I should have lost.

That's pretty much par for the course, tune won't change it. You need to pulley down to make more boost.

That's what I thought I'm not to worried right now about it since the engine is being built to run a bigger blower and more psi I was just worried there was a different problem.

You should get it retuned regardless. When you add LT's it changes the tune and lets you run more lean. It needs to be compensated for before something happens. It's not likely, but better safe then sorry, it'll also bring your HP/TQ numbers up. When I had mine done and tuned, I gained 43hp at the wheels.
