5-8 psi with stock injectors and an AFC would work, but you are going to be working those injectors sooooo hard. I am guessing you are using some sort of check valve also? This is not a good idea. 5-6 psi with the AFC is not so good on the timing curve and with a check valve anything after that would be not so good. Good luck with this setup. Be careful and listen for detonation.

If you are using the stock injectors you will need some sort of check valve. Using the stock injecotrs with an AFC isn't "the hack". You need some larger injectors to get away with running boost without a check valve.

I asked this same question in a post jus a few under this one. DR.BOOST also answered my question. Now I have the car running with turbo at 5psi on stock injectors while using the missing link. Before I go higher I am going to finish hooking up this SAFC and then put in the ignition system and the 450cc injectors in. But for now, its working...GOOD

If you have any questions DR.BOOST has the answer and I can offer all that I have learned.

Im running 450 cc injectors, and I cant get my car to idle right. I used the 10 wt 10 ohm resistors like in the "tech projects" section. Im running it with a vafc, tuned down near the -42-35 range. Can anyone help?

I think you need to have a lower resistance than that. Try using lower resistors. Are you sure the injectors are good?

Everyone I've known used 10watt 10ohm. I'm going to be putting mine in today.
