·As you guys know I've been having problems with my A/F ratio and EGT. I took my car to Bruce Nomura and we checked my engine code which came out to be 35 (no engine light was on, but we checked it just to make sure). we checked/dialed in BCC, did 12V fuel pump mode, and put the car back to bone stock except intake, exhaust, and DP.
I also installed Tomei A/F gauge with wideband O2 sensor attached at top of my DP.
tonight I went out to test my car. at full boost (16psi) hard pull on 4th gear my A/F ratio went from 11:1 (4000RPM) to about 12.7:1(6800RPM). then when I did a hard pull from 3rd to end of 5th my EGT still reached 730C boosting 17psi with 91octan gas.
any comments or suggestions?
thanx
