started leaning it out, and leaning it out, and leaning it out (i was on 450cc's with the honeycombs removed, i was plenty in the + side of the afc) all i can say is WOW. i got the car running 20psi now, .92v on the o2 sensor, and barely hitting 900C on the EGT. its a totally different car now.
1 question...
Should/can i run more than 20psi as long as my EGT's and o2voltage is good?
if you got a big intercooler, low 20s will probably work, but you cant get much more out of it on pump gas. i couldnt get over 21psi on pump gas without a bunch of knock, but my intercooler is only an 18r.
