Big difference in power. I get 3 to 4 mpg more when using performance level.

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 had bully dog before this one and it took me and my truck through the ringers. This product I should have stuck with since my first use in 2004. I love this product and will recommend to anyone.
