Wondering if there is anyone with a mark lt that knows if the edge evo will work on my truck. Edge says no and php says yes. Looking at a used unit but done know if it will work or not.

 

Not sure, but back in 03, Edge told me the Evolution would not work on my 2001 F250 Superduty with the 5.4 2V. It worked perfectly. I had a dealer send me one and guarantee my money back if it did not work. In turn, I left a testimonial on their website.

Here is a couple answers, looks like it will not:

But if PHP says it will, then buy it and let them put a custom tune on it for you!
