afc will work just fine at 6psi at stock timing using those 440'cc injectors.DONT WORRY. just because the engine is an f22 doesnt make that much of a difference, it acutally has lower compression so it can handle more timing advance. as long as your not detonating, theres nothing wrong with your timing to be advanced some, it will actually make more power. if you do detonate, just ADD more fuel with the afc.

now if you really want to be safe, add the btm to your setup and retard about .25 degree's at the btm and your set. id also recommend u get a bigger fuel pump.

oh and finally, if you only plan to boost 6psi, dont bother boosting your car. its a good starting point but youll get addicted very quick and want to turn up the boost. i hope that helps vato loco eastside gangsta crip .

 

cool, thanks for the advice...i doubt ill get addicted cuz i dont want to detonate my car...LOL...the stock fuel pumps are good up to 220hp tested by some company...so im good...still contemplating the btm..ill have to talk to the tuner...but thanks again

 

the higher boost you run on the AFC hack, the larger area of the stock ignition and fuel tables you use. if you look at the igntion table, the further right you go in the higher rpms, the less ignition advance you have. so, by running higher boost, your are essentially running *safer* boost.

engines dont usually blow because of boost (unless its very high boost), they blow because of detonation.

 

yeh i kinda figured most people would blow because of timing more so than boost...

so ive decided to go back and use the btm/afc
