Got Atwood 1.33 for the tune 30#, open dump, precision t3/t4 2.5 dp 3 inch MBS out. Removed the SAI and 2ndary 02 sensor -- 6 psi non intercooled.
afr's are in the 10's at wot 10 is the lowest it goes, it will say 10 or in the mid 10's, feels like its slow at wot compared to part throttle where its up around 12ish. I know its an old tune... Just want to see if there is anything I can do besides getting a new 02 sensor that might correct some of this.
The only code is for the emissions junk, which i know the chip will write out. I also have the SAI solenoid removed as well, not sure if that hurts.
I need the check valve that goes to the evap system, so its left open/disconnected. I also should get a check valve to the break booster.
Happy to be boosting, now to dial it in.
