Ok... I'm building a 90 240sx boosted SOHC with a T3/T4. CX-Racing kit. Well anyway, I am torn between getting a S-AFC and a e-manage ultimate. If I'm sticking with the stock cam, the s-afc should be allow me to tune it with larger injectors right? Is there a specific version of the s-afc you need to get? I've never used an s-afc before and just wanna make sure it'll be fine. I'm starting with 7-psi in the beginning but I wanna be safe and run larger injectors. Any recommendations for the T3/T4? 550cc would be perfect right or should I just get some 370s? I'm only going to tune it to 15 psi later so I'm just making sure this setup will be safe. If anyone has a boosted SOHC, could you post up some dynos/tuning setups? Thanks in advance. Also is it possible to use the Z32 maf with an s-afc or do you need to get a e-manage ultimate for that or would the sohc maf be fine with the s-afc and 15 psi?
