DiabloSport PC Interface - USB Cable Kit Reviews


Awesome piece of equipment but not for the novice.

Reviewed By Randy L (Orlando, FL) Reviewed for a 2003 Hummer H2 —6/21/2011 7:53 AM

Awesome piece of equipment but not for the novice. This tuner has the ability to fine tune almost every aspect of your vehicle. Without knowledge of the items it can tune for you I suggest: either use the installed program or download a proven program, or change it 1 increment at a time and thoroughly test the tune before adjusting again, just to avoid costly damage no covered by any warranty. Monitor the settings with the unit and create a log file and keep it for reference. With oversize tires, cold air induction, and cat back exhaust and predator i am able to improve my gas mileage by over 4.4 mpg with in town driving. And performance thru the roof :-)) AUTOANYTHING was GREAT TOO!

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).
