Edge
#3
First I had a Diablo Predator and sold it when the Edge came out, the Edge was hands down better performance. I sold it when I sold my 04' last spring. It worked well, left me with a no-start after one of their updates, but their customer service was great and got me going again quickly. I had the edge installed for about 50k km's total. I ran level 2 always with 87 octane, better throttle response, don't expect better mileage. It was worth its weight in gold while towing my trailer cause I could monitor my trans temps (among others). It was when I seen the trans temp hit 275F while towing my trailer through the mountains that I decided to get a bigger truck.
