Purchased The Diablo I-1000- for my 2010 Mercury Grand Marquis

Reviewed By Marcel M (PHOENIX, AZ) Reviewed for a 2010 Mercury Grand Marquis —4/5/2014 12:49 PM

This cover is excellent quality, I am very impressed with it. It Keeps the Ford dealer from "re-programming to default" my set performance parameters on routine maintenance visits. Or at least it puts them on notice when they see their code reading machine will not plug in.... Then then the mechanic will check the work-order that they failed to read in the first place, and see I TOLD THEM TO NOT TOUCH MY PORT!this will change my parameters.They leave it alone and all is well with the world. :)

Hypertech Speedometer Calibrator Reviews


Great tool for the job

Reviewed By Jimmy N (Rutheron, NM) Reviewed for a 2014 Dodge Ram —6/25/2015 6:39 PM

After getting rid of the performance robbing 20-inch wheels and tires and installing base model 245/70R17s, the speedo needed correction. Knowing the exact percentage of the change unfortunately doesn't help, so it's a bit of trial and error to get it right since tire height is the only usable criterion. With 30.6 inch tires, and no static loaded radius data, I guessed and used 30 inches. Very, very close. Tried with 30.25", but went back to 30, which is quick and easy with the Hypertech.
