Thanks guys for all the input so far.....I was leaning towards the Superchips, but now I have my mind made up for sure.

 

How come only one person mentioned the Predetor? I'm trying to figure out which one to go with as well. The Predetor is actually cheaper of the two.

 

It's good to see someone has actually tried different products compare. I agree these polls are more of a popularity contest.

I'd like to see what results you get with the Predetor. In the meantime, I think I'll get a Procal before moving up my tires to 265/75/16.

I was also considering the Viper throttlebody.

 

The AEV ProCal will probably not anything for you power-wise. It will can take tire size and axle ratio and reprogram the speedometer and odometer, so these are accurate again. It's also really easy to change the TPMS warning or disable it.



I moved from the Sport's stock tires to 33"s. Thanks to the ProCal, my speedo and auto shift points are correct now, but it sure doesn't feel any faster...
