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. :)

2016 f150 3.5 ecoboost

Reviewed By Jonathan L (NORTH ZULCH, TX) Reviewed for a 2016 Ford F-150 —5/23/2016 8:22 PM

Got this tuner after seeing the numbers diablo claims. Tried to install the tune but said update was needed even though I had already updated it. Contacted diablosport customer service and after 2 days I was able to install the tune. Installed the 93 diablo tune and let me tell you it is a night and day difference. Going to put it on the dyno soon to see what numbers I actually gained but it is definitely a noticeable difference.

You can feel the difference right away after installing the diablo tune using 90 octane. not so great on the cheap stuff but its worth the money easy to install and to play with no more lag after punching the throttle best part is the custom tune it really wakes up the engine
