welcome to the club lol take out 2 degrees wot timing from 4800 rpm up. i got mine holding 19ยบ to 4800, then i dropped it to 17 for the rest of the way.

right now ive got 04 comp g timing files, just turned down the bottom row 4800 up to 11's

if you installed a ported lim with the ic, thats where your psi went. i had 10-12 on a 3.4 with the stock lim no ic.
