Pretty good

Reviewed By josh l (Saint Petersburg, FL) Reviewed for a 2002 GMC Yukon —5/1/2010 8:34 AM

I bought this for my 02 yukon expecting better mpg and hp. I have noted a 4-5 mpg improvement for highway driving, but no improvement for stop and go/city driving. As for hp I have yet to notice a difference. I have aftermarket intake and exhaust upgrades on my truck and expected this device to make a noticeable improvement but it's just so so. I may connect a back up camera to it in order to get my money's worth out of it. The shipment of this product was also extremely delayed by the manufacturer and Auto Anything only notified me after taking my money. Bottom line decent product but high priced, crappy customer service.

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.
