[prostreetC-10]

Yeah right.....
Just want to make sure at least the stock plain spring is in the rear to slow down the secondaries. That booster config with the 3310 will be good. The straight leg is positioned a little higher in the venturi to slow the signal just a tad which is what you will want on that semi truck. High gears and no converter with big tires will have an effect. One thing I like about the 3310 is that is has big PVCRs like and 850. Will help with part throttle hesitation has you are trying to move that train. A slightly bigger PVCR will also allow you to run a little leaner cruise A/F ratio to help with mileage.......but not a ton. I certainly cannot tell you how it will work without being in my hands.
