ScanGauge OBD II Scanner Reviews


Perfect for my needs!

Reviewed By Chris S (Aurora, CO) Reviewed for a 2005 Toyota 4Runner —7/2/2012 8:19 PM

There's nothing worse in my mind than discovering a problem when an idiot light goes on because it's usually too late to prevent the problem.mThat's where the Scan Gauge II comes in handy for me. Now I can monitor my transmission and engine temps hauling my popup camper on road trips. Combine that with the ability to pull codes and clear them it's indispensable in my book. Already love the readouts and have had a couple friends buy one after seeing mine in action. There are cheaper alternatives but this is a case of getting what you pay for.

Bully Dog Triple Dog GT Tuner (49-State Legal) Reviews


AWESOME!!

Reviewed By Steve K (BLOUNTVILLE, TN) Reviewed for a 2002 Chevy Silverado —3/26/2015 7:58 AM

I had huge gas problems before the tuner because I drive a lifted truck and I was getting approximately 8-10 mpg and now in getting 17-18 I absolutely recommend this because not only did I get way better mileage I got a whole lot more power! HIGHLY RECOMMENDED

I had the exact same model from amazon and it kept shutting down. Returned it and got it from auto anything and it works great.
