So this maybe a dumb question but here goes. My 02's have been out a while. I throw insufficient switching codes all the time I know I need to replace my fronts with factory 02's But it smells pig rich and I think birds are dropping dead behind my SS. So question at hand if I use GM options and reset fuel trims will this have an adverse effect on my current tune? Or does it still keep it within set perimeters? Thanks.

And this is no way shape or form related or bashing my tuner!!! He's the most upstanding man I have ever done business with.

If you reset trims it will just learn back if the tune is off.
