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 inTune I-1000 Tuner Reviews


Great Tuner with only 2 drawbacks

Reviewed By Chad A (Renton, WA) Reviewed for a 2006 Chrysler 300 —1/20/2015 3:41 PM

This is a great tuner with many options. My 2006 Chrysler 300 SRT-8 felt like it was idling just a bit off for my taste. This tuner fixed it and made it purr like a kitten. I did not really notice any high RPM power improvements however it does accelerate off the line a lot smoother now. This was almost a deal breaker. You have to pay $120 to get a vehicle specific tune vs bama = free AND are there are ZERO options to adjust shift firmness (You have to buy another $260 tuner to do that).
