    Oversize fuel tanks

    I talked to transfer flow and they say that on every install they actually tweak the float arm a little to make the guage more accurate. This leads me to think that every truck will be different depending on how they set the float arm. I made new tables and also loaded a table from honda rider...

    Oversize fuel tanks

    I just put a transfer flow 45 gallon fuel tank in my 07.5. They put a new sending unit and float in it but they dont have the capability to change the miles till empty setting. The guage reads correctly but it acts like i only carry 26 gallons not the whole 45. So i look through efi live and i...

    Straight centerlinks

    Just installed a straight centerlink on a truck that has the bars cranked up all the way. It seems to hit the sway bar right at the joint from centerlink to inner tie rod. It tore the boot as soon as the truck took its first turn out of the driveway. Is there a fix for this? Im assuming just...

    LB7: Low rail pressure

    I have the same issue going on. I did the cp3 test today and it only gives me 15800 psi when i command the full 160mpa. If i give it a little touch on the go pedal to raise the rpms then the psi will start to come up. In fact the max reads at 25000. Is there anything else that i can test before...

    Tons of white smoke at idle and low rpms. Definetly fuel. With the cup issues that people have had, are you able to diagnose from efi?

    1093 code on 2002 lb7

    I finally got the engine to come up to temp today. I just put cardboard in front of the radiator and ran a few hills till it got to 197*. I pulled over and checked balance rates to see if they would read and they still wont read in neutral or park but they did read in drive. A few were at the...
