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

Screen is the right size.

Reviewed By Frankie B (WAVERLY, KS) Reviewed for a 2013 GMC Yukon —5/18/2016 11:23 AM

Fairly easy to download and install tuner. Screen large enough to easily read but small enough to not be obtrusive. Good menu services.

Hypertech HyperPAC Reviews

Useful product

Reviewed By Pavel B (Albuquerque, NM) Reviewed for a 2004 GMC Yukon —2/7/2008 10:33 PM

I bought HyperPAC hoping to achieve some performance gains and for the various diagnostics programs it offers. Installation is simple and straightforward, uploading performance tunes takes less than 5 minutes. Performance gains are consistent with the dyno charts Hypetech has on their website - modest but noticeable. I tow a trailer and acceleration from standstill and throttle response are better. My benchmark is a steep grade on I-25 before Santa Fe. With the stock tune the rig tops at 50mph on 2nd; after installing the premium fuel tune I was able to take it at 60mph. With this tune engine seems to develop more hp after 4000rpm than with the stock tune. I also like the engine monitor program which allows me to check on transmission temp. I also used the dyno program but you need to weight your truck for accurate results. Regarding fuel economy, there seems to be a modest improvement (14.2 city vs. 13.9 with the stock tune on winter gas-ethanol mix). In sum, I find this product to be useful and fun to use but do not expect miracles.

Edge Evolution CTS2 Programmer Reviews


Reviewed By Michael C (KANNAPOLIS, NC) Reviewed for a 2004 Ford F-150 —10/22/2016 5:35 PM

Had the original edge evolution, needed something that would run well with my intake and the cts2 did just that. A lot more power and response went from 11 mpg to 15 with this chip. Display is awesome besides the fact the truck has to be running in order to turn it on and the number of times you have to flip the key on and off during level change is crazy, have to turn on and off 4 times. But I don't change mine much so besides that I would recommend this to anyone
