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.

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.
