I paid a local guy to tune my beast, but that didn't turn out as well as hoped. I bought HP Tuners hoping to be able to dial it in myself. Even though it drives better, it's still far from what it should be. I have a wideband O2 installed, but at 70 this stuff is just too much. The truck is a 68 Kaiser Jeep M715 with a NV4500 trans, Mercruiser HO cam and 42lb injectors. I'm hoping there's someone willing to helpout for a reasonable cost.
