Magnuson pulley change

Recommended Posts

Thinking about changing my pulley from a 3.2 to a 3.0. Will I have to get retuned? Living in rural Manitoba Canada makes it very difficult. Guy I bought the truck from said it was tuned at a performance shop before he bought it. The hand held tuner isn't with the truck. Has 202,000 km on it and is a weekend cruiser and sometimes daily driver. Has Kooks long tubes, high flow cats, airaid intake, msd wires, built trans. Don't have a boost gauge on the truck right now. Really cant afford to take the risk of hurting the motor.

Re tune, but you can drive it, you just have to watch the A/F ratio.

Me personally. I would put on the next one up from the lowest pulley you can put on for max boost and tune it from there. If its a radix SC instead of a 2.75 go with a 2.8 and tune it there so you don't have to continue to get retunes every time you want a power increase. I also us my tow haul button as a performance bump for racing.
