ok i would like to know if any of the performance programers have the setting for tire size i got 325/70/16 on my truck and was wondering if they had the option on them. or if it doesnt matter if things like lifts or any thing effect the power of the programer. i was thinking of running the predator
The predator to current does not offer tire size change. But i am sure in the future you will be able to download a update that will support it. I think that the super chips does but am not positive.
And a lift will not change your performance(just areodynamics and stability) but the larger tires will, its just like changing your rear end gear ratio. The larger the tire the more it has to spin to achieve the same result as a smaller tire. Plus its heavier.
Check my gallery, I qualify for the lift and tires. I have the Predator and run 35 inch tires. Speedometer is 3 miles an hr slower with no effects on performance.
Hope this helps.
Going from stock steel rims to aftermarket aluminum, the rolling weight is the same on the taller tires. FYI
Actually you do not have to worry about tire size/problems untill you go to 38's and bigger. I have been running taller tires since 1977 on my trucks. I did a gear change to 4.10's on my 79 running 35's, but it is a gasser. The 6.0 runs great.
