No major problems with it

Instruction manual was incomplete; did not have my Astro van listed. Called help number and they helped me. Can't really feel any difference in performance. Haven't checked gas mileage yet.

This is the first time I have used this product. It was easy to install and it has given my 1999 Silverado 1500 quite a bit more pep. We will see how things progress over time. Excellent customer service from this business. I will come back in the future.
