Just installed the edge 'w/attitude' in our 2004 lb7. This is a blast! no other performance mods planned yet though. In the next couple weeks, a 6" RCD lift is on its way, and 35" tires. I am really looking forward to learning more about how it works and the different settings. Im interested to hear any reccomendations for de-fuelling percentages and set points? I got a smokin' deal on this product, and I like the adjustability features. I didnt get it to race, not really into that, but I like the extra zip its got now. on occasion, we tow a jeep and trailer, or a couple sleds, so not much super-heavy. Anything to watch for, or keep an eye on => EGT's, Tranny concerns, other drivetrain? etc?????
