im using an safc for fuel management and when i reach around 7,5 psi i get a cel , can i use check valve on the map sensor or a missing link to raise the boost higher to fool the map sensor ?

No. What elevation are you at, and what settings do you use on the SAFC?

a missing link will cause u to have detonation, as i just found that out my self!!!

i dunno about elevation but on the afc im running the leanest i can ... -30% for all 6 **** and running 390cc inecjtor .. about 8% too rich still..

You cannot use a check valve and an AFC. I got my ---- straightened out by Mr. TurboEdit himself when I tried to suggest it. :P If you want more boost, you're going to need 450 cc injectors and a digital SAFC. And if you want more than approx 8-9 psi, you'll need a new map sensor and programmable engine management (or a fmu, check valve, and a pair of big hairy *****)
