So the AFC hack does advance the timing a bit!?! So you might just wanna knock it down at the dizzy, right?? Good, info, a lot of people needed to hear that cuz there was so much this and that about the AFC hack.

1degree is too much. i was runing like that with the ghettodyne and it was wack. if your car can handle the 7-8 degrees advance without detonation then leave it. youll be makeing more power. you only need to retard if your having problems with pinging.

Damn, well I have three options, right now I have an automatic PR3 ecu so it fuel cuts at 7600rpm's and has a speed limit which pisses me off. So I can either:
A) Use the J. Davis chip that I have even though 1 degree retard per pound of boost is too much, maybe advance the base timing 2 degrees?.
B) Find a stock program to get chipped, set my timing at about 2 degrees retarded and run 93 octane possibly being fine.
or
C) Use my nasty automatic chip, set timing at 2 degrees retarded, and never feel what it's like to run higher than 7600RPMs and faster than 113mph.

Is that J. Davis chip one of the ones you can reburn? If 1 degree of retard per pound of boost is too much then reburn the chip for .5 degree of retard per pound of boost or around there.
I thought I read the afc advances your timing more at low boost as well. Like 7 psi and under.

Re:dynoed actual advance that a v-afc puts out at 10 psi
sorry guys should of cleared taht up the peak is 7.2 deg advanced at roughly 5-6 psi the starts dropping dramatically to almost no change at 10 psi about.8 and th9is want my dyno it was my boys and i actually was there and seen everything so its not fake the numbers where 215.1 hp and 161.6 lb torque so if your looking for 9-10 psi then go with the afc hack if not thenuse other fuel management cuase it can hurt you if your not carefull and hopefully soon ill get the graphs to post them for you guys
