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

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.

I have a '08 F150 4.6L and I had just bought a 27' RV and it was putting a huge strain on my truck in the hills and mountains of Tennessee. I purchased CTS2 along with volant cold air intake before a vacation to Florida and WHAT A DIFFERENCE!!! The tune for towing saved my truck from killing itself to pull the RV. Rpms never went above 3800 even up the steep hills...if your towing anything this chip makes a world of difference I would recommend for sure along with autoAnything...great service!
