CAMARO6 - View Single Post - Reflash ECM for Speedometer Recal vs Power Train Warranty???

I’m pretty sure I know the answer to this one but gotta ask anyway.

I want to buy some BFG Comp2 A/S for driving in the cold, wet months but they only come in 35 profile. My speedometer would be off 3-4 mph which would really bug me.

If I have the ECM reprogramed to adjust the tire size on my 2018 ZL1 do I risk voiding my power train warranty?
