I ran a Jet module in an '86 truck with a 318. I got better fuel mileage & it picked up the performance a great deal, in my opinion. Prior to the mod change, it wouldn't pull a string, after the change it would smoke the tires from a standing start. I haven't dealt with them in many years, & things change. This was just my experience 15 years ago.
