4 to 8 cylinder switch

    Anyone know of a way to install a switch to control the 4 to 8 cylinders on the GM fuel management engines? Since just the A/C cycling will create enough of a load to demand the 8 cylinders turn back on I want to control it and keep it in 4 cylinders at those times.

    Next question or statement, my 03 burb got better mileage then the 07, anyone have any mods available to increase the gas mileage?

    Thanks

    The best mod for gas mileage increse is ease up on that right foot. :great:
    But since that's now fun, Programmers,(Hypertech, Edge, Superchips and so on) Intakes, (K&N, S&B, Airaid) Free flowing exhuast and other simple bolt ons will net you a little increase and a little HP while your at it
