81 seems reasonable for high trim, but not for all trims. The ECU reads both 02 sensors, hence the two 02 sensors.

My mainscale is at -60.5 which lets me basically not touch the low load tune, cruise(on flat ground) at 14.7-15.1:1, and casually accel at 13.2-13.6:1. But there is a point when casually acceling that if you press the throttle past it, the car says no and I will see like 11.5 afrs
Are the mid loads coming into play while going up hill? Does map enrichment effect anything besides tip in?


Should I be messing with the VE table? Should VE table #2 be working for me?(td05 headers, 16gs, o2 housings, downpipe, 3 inch all the way back)

I'm using 4.85 or something, I'm going to try 5.03 when I have time.

This is not like a SAFC. Use the VE table.

It sounds like your tune is really fucked up and you probably want to start over. You can't just use old VE tables when you mod your car. You especially can't use other people's tables. You need to tune and make your own VE table. Use someone else's to get your car running, and begin tuning immediately. That should take care of some of your issues. Also, I'm not sure what your doing by running without 02 sensors. I'm not familiar with that strategy.


BTW: My mainscale is about -60 and my car is in the low load part of the VE table all the time while cruising.
