Car is running rich and throwing a maf code. But car is a SD tune OK car is a 06 GTO with a procharger running a SD tune
I thought i fried the front 02 Sensors Because it was running rich at idle and part throttle causing it to surge and buck some times . So i replaced one 02 sensors seemed to work for like 5 mins then started acted weird again.
Ive ran a mixed of leaded 116 and 93 pump at 50/50 mix for like 2 years just burnt out the 02 sensor. So how could i burn out the new one in 5 mins
There no check engine light but i hooked up a scanner to see if it had any codes
MAF code / volume of air code. But i dont have a MAF any more?
Also thought a emissions evap code i think. But i dont have that either

Change C2901 & C2902, high fail limits & C2901 & C2902, low fail limits for MAF to eliminate MAF fault. Any amount of leaded fuel can fry 02's in a hurry & may eventually clog injectors.
Evap, set B0501 higher than highest coolant operating temp & dissable B0505.
Don't know why your PCM is using 02's w/ SD tune except if B4206 is not dissabled. So, dissable B4206 unless there are idle problems without using the 02's during idle. If your car needs the 02's during idle, then you're always gonna fight the fried 02's while using leaded. Have you tried straight 100 Octane + some Toluene to increase the Octane (each 10% Toulene = 1 Octane point, generally)? This will not fry the 02's, if you actually need them.
