Re: 1991 V3500 Project Heavy Hauler

Made the deadline, got the headers on and she is tuned. Pretty noticeable difference. Fuel map corrected, timing added, shift points adjusted, idle smoothed out and probably a few other things I'm forgetting. Guy knocked it out in a little over an hour of driving and stopping. I'll do a video once I get the exhaust fixed (flex pipe) and have some time. Even with all the weight in the back she smokes the tires from a standstill by mashing the gas.

PS Thorley came through with the right gaskets in time to only do that once. Yay customer service!
