I have been running the Jet on my '97 Dodge Ram with 5.9l. I had previously added a Holley TB, Venom Injectors, Spectre CAI, Accel coil, Gibson shorties with Flowmaster, and some new oxygen sensors. Called Jet, and they could not recommend the installation. Works great however, best with premium, but I have run 89 octane without pinging. Stoker!
Jet performance programmer is a must have upgrade!!
I was sceptic about buying a programmer for a 98 4-wheel drive Tahoe. I went ahead and purchased this unit and was suprised at the performance and overall options this easy to use programmer had to offer! I highly recommend this upgrade for any vehicle.. Charles.
