Since I run the edge, i can only speculate, but Predator sure seems to be popular. That or the PPE. If i went the programmer route, i would go PPE. Reason being is it will stack well for really big gains.
I've got the PPE Xcelerator Economy version. It does everything the Xcelerator does except raise the rev limiter, hp is slightly lower, and uses stock fueling. Power is smooth on delivery. I'm very happy w/ my purchase for 450. Good Luck
I have had my superchip for a few months and love it. I think it's a great programmer if you can find a deal on it. The truck drives like stock. I don't notice any surging and there isn't alot of smoke. I have it on the middle setting and the power is great.
