Changing the resistor is just like turning up the fuel on the older manual injection pump. PROVEN effective by diesel enthusiasts everywhere. (aftermarket scam #13 will trip an SES code) Unlike a gas engine, with diesel engines, the more fuel injected, the more hp produced.

The #9 is the largest value available. The OEM states a 6% increase in fuel delivery over a stock #5 at full throttle. #1 thru #9 resistors adjust the fuel rate output your injection pump. Used in Chevy and GMC C/K pick-ups, G/P vans and cab/chassis (buses, etc) and H1 Hummers with electronic fuel injection. Fits all GM 6.5 turbo diesels 1994-2004 with electronic fuel injection.
