That's good to hear. 14 psi is where I'll probably try to land as well - should be decent power on the 2871. Speaking of which, how did everything fit? Also, are you running a custom map on the AFC or are you using one of the pre-made ones from the AFC thread? Just curious how you're going about tuning with them. I assume the stock ECU can still compensate for the added fuel at idle?afc is doing ok with the 440s, i am dumping way rich at around 3500, but i lean out and run really good after 3800 rpm, until i get the fmic, i am gonna stay around 10-11 ish, but once i get the fmic, i am planning on 14 psi. it feels really good right now, i am doing some easy driving, then i am just boosting for a lil bit to 7 psi. really like the feel! much better than stock, plus i have not had fuel cut once.. hahaha!
