S-AFC vs. JET V-Force PCM on turbo GS!

what do you guys think about the comparison between these two tuning piggy-backs on a GS w/ turbo running 10 psi?

also, could either of these take the place of a vortech sfmu so i could simply run either one of these piggy backs with the fmu that comes with the star kit?

Ok the Jet PCM is complete crap and will do nothing for your car at all. The only thing they will do is put a jut sticker on it and send it back to you. You are talking about the JET "re-programed" ECU right? The SAFC you can use, but you have to be careful when leaning the system with it because it could advance timing and lead to a blown engine under boost. When you go to larger injectors, Like you should be to be safe at 10 psi, you will want the SFMU because it has the abbility to set idle fuel pressure. To be honest with you I would just get the FMU and do my fuel that way, with an SAFC for VERY SMALL adjustments. Are you still on your stock internals and injectors?

i would like to upgrade to 310cc injectors but i am not sure what my options are with that because i am a little short on cash so i am trying to spread out what money i do have over the long haul. but like you said in other other thread i could run with the FMU with no other addons at 310cc injectors with out any problems...i think
