Review on Jet Performance 294296P Chip Computer by Lamar Hopkins

with Flowmaster exhaust (each). I am currently giving TWO stars as I need to return this item and try a different part number. I will update upon return and the new one will be installed and checked for issues. However, I love the product when it worked. It was very easy to install. Unfortunately it was the wrong part number for my car, although the website and research showed Revain to fit my car. It worked fine for a few days, but then the Check Engine light came on and transmit performance dropped. I had to disconnect the battery to reset. After two questions to Jet customer service and tech support was very helpful they listed the wrong performance chip based on the stock part number. So I suggest you get out of the ECM and call Jet directly to get the correct part number to order this chip. They are sold at many retailers so it is important to have the correct part number based on your particular vehicle's exhaust part. The correct part I just ordered here says it doesn't fit my car but I'll use what the experts suggested. Addendum: 3 stars. They accepted my refund request within 24 hours with a free shipping label. .Last update, the truck works fine, should use 89-93 octane for better performance and fuel economy, but it gets up and drives. Thanks for the quick return and sending the right part
