Quick and easy install.

Reviewed By James W (Kingston, MA) Reviewed for a 2002 GMC Envoy —9/8/2005 1:05 PM

Installation took a whole 10 minutes, max. Unsure about exactly how much HP gained, but it does "feel" quicker. I did the K&N intake and Borla cat-back shortly afterwards. Both recommended.

Lots of options

Reviewed By Kenneth F (HENDERSON, KY) Reviewed for a 2011 Ford Ranger —4/15/2015 4:25 PM

Really a nice device. I am amazed at all you can monitor with it. My main reason for purchase was to monitor the transmission temps when towing my 17 ft travel trailer. But I'm also monitoring fuel mileage and throttle position. I only gave 4 stars because the included velcro for mounting allows for too much vibration. Replaced it with a 3M Command strip refill.
