ok here is whats going on, ive been boosted on 6PSI on a completely stock b18c1, except for a skunk2 intake manifold and a 68mm TB (which measures to really be 66??) for about a month and a half now, got it tuned recently by Phiz ( which by the way i would recomend to EVERYONE, GREAT person to deal with...and has cool hair ) so the scenario is this..should i raise the boost with a 7.5 spring going in a 35mm tial WG, or get a manual boost controller to up the boost? or option C..leave it at 6PSI, motor has 115K on it. new head gasket at 98K, head was cleaned and did not warp from the blow head gasket. oil change ever 2k with mobil 1 10w30 fully synthetic. the setup is as follows:

keep in mind new head gasket at 98K...

B18C1
skunk2 IM
68MM TB (measures to be 66)
turbonetics t3t4 from revhard stage 2 kit
revhard manifold
35mm tial wg with 6psi spring

2.5 DP and 2.5 full exhaust (no cat, 2.5 test pipe)
greddy type S bov

i would get some arp head studs and a thicker head gasket and then you can probly run 10-12psi, thats what i would do if my motor was stock and i wanted to run more boost, and you should have it retuned also when you turn it up

are you sure about retuning, the map collumn is from 5.5psi-8psi..running 6.3 now..which seems to me to be in between 5.5 and 8, making it safe to boost 7.5
