Programmer? I have a 2007 Chevy Tahoe Z71 5.3L, I installed long tube headers and got rid of all O2 sensors. The engine light is on and I no why (02 sensors) but the fuel mileage is still above 18-27mpg. So no big deal! V8 mode is the only mode that works, V6 mode will not because the check engine is on. Now my question is, what programmer is best to erased O2 sensors all together by adaption the performance it has, turn off the engine light and add power and performance?
