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'm happy with the Superchips. Combined with the Boost Stick it is all I need until I can afford to upgrade the tranny.

I recommend checking out a switchable EFILive tune from Kennedy Diesel or one of the other EFILive tuners. You can pick and choose power levels, tire size, limiters, etc. to fit your needs.

No need to buy additional tuners or boost sticks if you go that route.

I don't currently have one on the DMAX but I ran a superchip on my F250 and it worked great.

A vote for the Predator version 2.02 here. It does more than I need it to.


At least, until I get a Suncoast V...

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.

Edge EZ or Predator 2.02. If you choose the predator then keep it 65hp or below on the stock trans if you want it to last for a long time.
