Hey everyone, my edge ez amp just died, i have had it for 7 yrs in my 01 gmc lb7. What i'm looking for is suggestions for a replacement. I have 150,000 miles on the truck now, with a 6" fabtech lift kit. thanks in advance for suggestions.

are you looking for max power output or fuel milage?

Highly recommend Kennedy Diesel's switchable 'Tow/Haul-Ass' tune for the LB7, with the adjustable boost valve.

Don't do anything too crazy with this 2001 in its 'old age', or you'll likely do head gaskets...
