HPtuners Credits

2006 Jeep LJ 4.0L

It took a while to get all the bugs out of the engine before I could actually install the tune. It feels like a lighter car with so much more responsiveness. Fuel economy is maybe 1 mile per gallon better but you gotta consider the performance factor and the fact that I went to 35 and added more weight. Overall, I think it’s one of the best upgrades I’ve installed.

Great company

Got all my credits, tune for the vehicle and everything else I needed to finish my engine build all in one spot. Great response times on remote tuning and fast shipping. Will definitely use FRP on my next engine build as well.

Customer Service

Always put's the customer first!!!
