I have a 03 h2 with a AfE intake and magnaflow exhaust and now its time for a programmer. Im not sure witch is the best fit? I have been told superchip but not sure? Any ideas?

 

I have an 03 H2 with magnaflow exhaust, a custom CAI I use the Predator Diablo. Specifically i'm using the U7195 model. Love it, love it, love it...

Might want to check eBay and some forum classifieds for them. Occasionally ppl sell them for cheap. I got mine new for $299 at my local shop

 

Do you have any problems with check engines lights coming on with it? I have heard problems with diablos such as that and hzve to always unistall and reinstall. Also was it much help with fuel mpg?

 

I just installed the 87 tune in my 03 h2 , only upgrade was a airaid cold air
intake. with a roof rack i was avg 12.5 made one trip so far and its up to 14.2
will see if it holds to that . i did notice that the tranny shifts are a lot smoother .mike

 

I have been hearing nothing but good about the Diablo! I am still just hesitant about it cause from my part of the woods no one has them but the one person i have talked to. I live 5 miles from BullyDog so that is what everybody runs and thinks is cool. I honostly dont like BullyDog!! I have had powerstrokes in the past and have always ran Edge Products. This gas thing is all new to me!

 

I run the Predator on my 2005 2500HD 6.0 pickup and like it, but am hesitant to run the Predator on my 2008 H2 with the 6.2 engine. The 2008 owners manual says the 6.2 is supposed to run on 91 octane minimum. The Predator programming choices are 87 octane or 93 octane. If I program it for 93 and can't find any 93 octane, I am apprehensive of too much engine knock. And I am not sure if running 87 octane gas would be okay in an engine designed for 91 minimum octane. I am not sure if they have fixed it, but one thing I don't like about the Predator on my 2500HD is that anytime I change the program it resets the engine hours to 0. A minor annoyance, but the Predator folks say that's the way it has to be.

 

I run the Superchips Cortex in my 08 5.7ltr and love it...gained nearly 5 MPG and some power on the 86 tune. Do not recommend the economy tune....no power....have not tried the others yet.
