I just bought a used truck that, to save fuel at low power, goes from 8 cylinders to 4. Lots if problems with that. I researched the various blogs and found a guy that would reprogram the computer to turn it off and run V8 all the time.
$50 for him to reprogram my computer AND it included shipping back to me. Granted, it took him probably more time to repack and label the box for my truck’s computer than it did for him to reprogram it - but $50 well spent IMHO.
I’m guessing most anything can be changed with the various sensors and safety features. (My truck was off the warranty so that is a big deal.)
Hmmm. It is an enticing thought.
