Application Guide
The TruSpeed addresses all speed signal-related problems; it doesn't just correct the speedometer. How? The TruSpeed module installs in-line with the factory electronic speed sensor and converts the wrong speed signal into the correct one for your vehicle's new tire and/or axle gear ratio combination. Because the signal is altered at its source, all speed-sensitive vehicle systems will receive the correct speed data, which restores all proper functions. The TruSpeed is available for most domestic and import vehicles equipped with an electronic speedometer.
Main Features
Corrects speedometer / odometer readings, and the speed signal sent to the engine, Powertrain, and anti-lock brake control modules. Besides the obvious, these modules affect fuel delivery, engine timing, and automatic transmission shift points.
Eliminates speed signal related reductions in engine performance and fuel economy, as well as related changes in exhaust emissions
Infinite adjustability provides precise speed signal calibration within 1%
Two settings allow off-roaders that seasonally run different height tires to correct their speed signal by flipping a switch
Simple four-wire hookup
Includes complete instructions and adjustment charts
Can be recalibrated infinitely for future tire size or gear ratio changes
Works on most vehicles equipped with an electronic speedometer

2001 2500HD. Bought Predator that claims they could fix the tire size by going through the ODB port, all they did was make the speedo worse - read their forums first and see how it worked out for others. Got this item instead and after getting it installed - which is scary to splice into wires at the computer - it adjusted the speedo like a champ. Shifting is improved, I don't fear the police being behind me with an improper calibration; it was worth the effort on the installation. if I ever muck with a tire size too big to be adjusted by the dealer in the future, this will be on my list of items to purchase.

These are the best thing ever. It fixed poor fuel economy. I went from 9 mpg after the lift to 16mpg. It also fixed sluggish shift points and corrected my fuel reading. I think all should use these. I have recommended to 2 friends and think you need one if you have changed the tire size from the ones that came with your truck. I have a 2004 F250 SUperduty 6.0 Diesel...
