OK when I accel hard in 1st gear I only hit 5 psi and max out 2nd, 3rd and 4th at about 8 or 9 psi.

hmm, has it just started doing that or has it built boost like that always. it seems pretty normal to me. no turbo car makes much boost in 1st. and 8-9 psi seems about right for your mods. i think. im assuming a hi-flo test pipe is not an open midpipe. anyway one problem could be your blow off valve. ive been told they leak boost at 9 psi. i know when i swapped to a blitz aftermarket BOV my car built boost much better and held more too. just my thoughts.

 

HUMMM I havent ever heard of the apexi bov leaking boost but I am going to try to get more info on that now.
The mid pipe is a 3" piece of pipe welded in place of my cat.
Where did you get your blitz and how much was it?
I would like to get one of those because I know that they are alot louder which is cool!
Thanks for your thoughts I appreciate the help!
Thanks,
Josh

 

normal. boost is made by load. no load in 1st as it goes by too fast.

 

1st usually won't give full boost.. 2nd usually won't either.. 3rd usually gives full boost, 4th starts to creep, and 5th really starts to creep
