Installed on 2006 Sierra

Reviewed By Michael S (Neenah, WI) Reviewed for a 2006 GMC Sierra —6/30/2013 7:51 PM

At first I wasn't sure if it really was working cause I couldn't really see big changes but after about a month I noticed the mpg gains. The power increase was quite amazing too. I feel this is a great product and as they say" you get what you pay for ". Already thinking about upgrading to the IQ.

Jet module

Reviewed By Joseph L (Brownsville, TX) Reviewed for a 2016 GMC Sierra —5/24/2012 4:00 PM

I recently purchased the jet module and have seen an instant change in my truck from the idle to the response when needing to floor it on the highway. I have to drive 20 miles back and forth to get to work a day and before the installation I would need to put gas every five days and now I going up to 7 days before putting gas again. This is a great item from just trying to save gas to wanting some extra horsepower. The installation was very easy and had no trouble putting it on, about 10 minutes to install.

Difference noticeable

Reviewed By Donald S (LUVERNE, AL) Reviewed for a 2016 Nissan Titan XD —12/11/2017 8:14 PM

The power torque and horse power is very noticeable. The stock setting seems to add about an average of 6 mpg if drove at 60 mph, also with slow take off from a dead stop. Those averages go down slightly as I go through the spot and spot plus. Now as for the race setting, very powerful and noticeable from stock setting. Fuel mileage goes down to about 19 mpg. However, speed gain is very quick.
