I'd give Edge the nod for the most power in a diesel, I think Superchips is the safest. I've tried Predator in a 2006 Ford diesel and it was impressive. Duramax from what I've seen, is compatible with most modules and downloaders. Ford 6.0L PS is the touchiest and riskiest to modify engine controls. I may test Godzilla next, it just seems a little complicated. I'd recommend installing a Piro, exhaust temperature gauge and adding aftermarket free flow exhaust to get rid of some of the heat that increasing fuel pressure and changing timing can add when chipping. Then there is the warranty issue. You have the right to improve your vehicle as part of the Magnuson Moss warranty act of 1975. Some dealers try to void your factory warranty when you add aftermarket products. So the question is how far will you go to defend your rights. If you don't want the hassle, you may not want to get carried away with mods. And if you are leasing your truck, you can't modify the performance. This is why alot of folks take chips off their trucks when they go in for service. Not necessarily to hide the mods, but to eliminate the hassle if a service manager wants to blame an aftermarket product on a factory component failure. Also if a service manager wants to void your warranty, they have to give you in writing, their evidence that your aftermarket modification caused a factory component to fail. So before the hate mail comes in on this controversy, I'm in the dessert in an undisclosed location driving the new 07 Tundra. I'll be towing loaded horse trailers tomorrow. So no email for many hours. Back in OK Friday at the World Show. So stop by and argue with me. |
