Back on topic, sort of, Stealers will do anything to wiggle out of responsibility and GM at the very least turns a blind eye. So be very careful and or sneaky if you are tuning while in warranty.

Having discovered it later, I thought I had snuck in under the radar only to get smacked by reality later on. Learn from my misfortune and lack of diligence.
