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.
Its an ok product with minimal results

I bought it so i could adjust my speedo for my bigger tires and 410 gears. It was easy to do that but as far as performance gains i have yet to notice any. Not thrilled with the cost to hp gain ratio.
