This was going to be a presentt for… This was going to be a present for someone. I have a long background in everything automotive, I know auto repair technicians who are independent as well as shop owners. A few YouTube channels did exclusive investigations on this FuelPro using test equipment. The product failed miserably, and the inside identifying electronics were intentionally scratched off while other connectors were attached to absolutely nothing. With 3 LEDs blinking, it's a repetative light show. No matter which model of this "fuel saver" is purchased/used, you pay for a light show. Some reported permanent car electronics damage. A YouTube channel owner in Australia did an extensive research reporting "you're paying for an expensive light show under your dashboard once plugged in". His tests proved there was no gas savings or performance improvement. A $50USD purchase up to $415USD is better used for a properly tuned engine with higher performance parts, the same with the transmission whether automatic or manual (clutch), a 4 wheel, wheel alignment, larger exhaust pipes & muffler, all improve a car's performance. A blinking light gadget will not.

this is good,verygood and best -

I should have never bought this I should have never bought this; it made no difference. It actually made my car run worse. What a waste of money.

Comparison Reviews It is useful to have a neutral party review these scam-ridden products, so thank you. One extra benefit might be to compare products that receive similar customer ratings (at least the better ones). For instance how does the GTE Stage 1 compare to the JDM Stage 3 at twice the price? Keep it rolling, Trev
