DiabloSport OBD-II Port Cover Reviews


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. :)

DiabloSport Trinity T-1000 Programmer Reviews


Good but pricey!

Reviewed By Aric M (Hanna city, IL) Reviewed for a 2011 Chevy Silverado —6/2/2015 3:30 PM

This was pretty good programmer i could really tell the difference in acceleration and power. I have not had it long so still unsure of mpg gains but it seems like a tank of gas goes further than before. Was a bit expensive but at 20% off had to try it!
