the idea is to get one or another. VMP does offer a hardware trade in...

 

you might want to get a dashhawk to monitor all all of your temps and other things.

 

How can the truck have power from just one terminal?

 

I was thinking that it retains a little bit of power until it is disconnected....maybe???

 

I realize that after doing a bit of research. Lol. They are both tuners in them selves.

 

There is still power if the negative is connected. It just doesnt complete the circuit. I dont remember how it works, but i learned it in automotive school. In order to do anything you disconnect the neg. disconnecting the positive wont reset anything. You need to disconnect the negative.

 

It does reset it because my CEL goes away, my clock gets cleared, ect.

 

My suggestion definitely would be an Xcal III and Troyer custom tuning. However, if you need it quickly then VMP is getting some very good reviews. I am thinking about ordering a couple tunes from them simply to feel the differences between VMP and Troyer.

 

I think I am going to call AEM and see what there opinion is on this first. I will be sure to keep you in the loop though.

 

This may be a day late and a dollar short, but wouldnt the CAI cause it to run lean?
