Just installed a egt that works finally. I was wondering what everybodys running on they're sr20 egts. On a 90 degree day at wide open throttle my egy jumps to almost 1500. I'm pretty sure this is fine but I was wondering on stock internals what the most the redtop can handle 1600? I have a gt28rs with 555 injectors and I still have a ka24e maf. Going to install a vg30e maf soon. Also I'm running in between 12.9-13.8 air fuel at idle and 14-15 at 3500 rpm.

care to elaborate on this? it doesnt sound too good. Idle should be alot leaner (15:1ish) and on boost it should be around ~12:1

yeah, my air fuel ratio was done with no load, thats why the numbers are messed up. I dont actually own a wide band so I was just borrowing a friends so I couldnt even test it while driving.

I was wondering did you change your headgasket or anything to run 17psi? I heard the stock sr can only hand 15psi the way it is.
