First things first. I love this thing!!:ro) It is truly amazing the power difference even on level 1. Pretty much from the get go , I have kept it on 3x3. I have had it on for about 200 miles, so I figure the tranny has learned the new power. A couple of times I have bumped it to level 4 and the couple of times I have gotten on it, and not even full throttle, it seems like around 3rd or 4th gear it's like I just let off the throttle. It can't possibly be limping because I am not much over 1/2 throttle. Is my tranny still "learning" or is it something else? I haven't even tried level 5 yet. A little cautious I guess. I did move the boost setting to 28, because at 25 in level three it would easily hit that and flash. I have kept the low end fuel setting on 3, from the factory. Do I need to be in 5 or would this not make any difference? Also, I have gotten as high as 26.5 on the boost. Is this ok for an otherwise stock truck? I know some of you out there will say to just go out and play, but still thought I would ask. Jerry.

I'm in the same boat as you are.
I'm still playing around with all the levels and all the different things on it.
I just installed the Edge also and probably have about 300 miles on her.
I'm tried all levels ......5 WOW. If I don't be careful I'll end up in the moon or loose my transmition.

ACE21, how long did you wait to try level 5? Did you just get on it from a dead stop or ease into it ? What is your fuel setting at? Jerry.

i also just installed the edge and i noticed doing the o-60 thing that it was only faster by 1 second between the 4 and 5 settings. i was hoping the turbo would spool faster but it didnt seem to help much on that.
