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. :)

It does what I expect and more

Reviewed By Erik R (Anza, CA) Reviewed for a 2009 GMC Sierra —5/16/2015 1:43 PM

Dang. I didn't realize there was a 500 character limit. So I will keep this short and sweet. Power 5 Ease of use 5 Tuneability 4 Instructions on what does what 3 If you don't care about your 0-60 times and yada yada buy this tuner. Oh! Do NOT adjust your tune if you have smog/state inspection coming up. They don't tell you that if you adjust parameters you will fail. It took about a week for my truck to go through the "GM cycle". Great buy, autoanything rocks
