After-market engine "fixes" mostly are good at just one thing: Getting money OUT of your bank account. That goes for oil and fuel additives too.

GM would not have put on an air intake system that harms the engine performance.
Fuel additives not needed? Leave FL and go north in the winter w/o this in a diesel, see ya in the tow yard.
