i put a edge juice with attitude in my uncles 05 lly and it is a 6speed manual i put it on level 5 120hp and it just don't seem like its got that much power and it only smokes a little and it does not even slippe the clutch something can not be right with this edge. and i mean know power i have a 96 12v with a 5speed that feels like it has more power.

 

Is it taking longer than expected to light the turbo? Try level 1, then go to level 5 and see what the difference is like.

When I did the edge in a 6.0 Ford, it starts out slow then rolls into it at about 30 or so. My nephew's 06 5.9 is the same way. Takes a few seconds for it to roll into the power band. Yo might also try checking the connections.

 

also if the truck is cold the edge wont give any power till it is warmed up. i have an auto and it dont take off like a raped ape till it shifts down and revs up to 2k or so.
