Can Crower stage to Cams make me run lean?

[RichL19]

I'm currently rebuilding the head on my car im installing corwer stage 2 street/strip cams, crower springs and retainers, and fidanza cam gears my question is will the cams make my car run lean im runing all stock fuel system and planing on runing 15 PSI on my 14B. Will i have to get an S-AFC to compensate for these cams and boost.

well, i am not gonna say you will run lean. but more than likely i would expect to see the car run leaner. you will get more airflow into the cylinders, especially in the top end where higher lift really helps.

i would definatally advise running a datalog on it and see what its doing. there is some room to play with stock fuel/stock ecu, so you might be fine. but like i said i would datalog it.

I just recently installed a set of BC 272's and I had to add up to 10% fuel on afc lo points to get my fuel trims at 0 and my hi's are like in the 13-14% and thats on a b16g at 15 psi with 560's and a 190 pump and KD chip
