I installed the Evo last night and it was a breeze. Already had a thermo tap in and the hardest part was removing the old Recon system.
What they advertize and what it shows for power are a little diff though. About 1/2-2/3 the stated HP gains for the LBZ, the LLY gets more.
I do like the display and it seems user friendly
