I have a 03 electriglide and just finished cam upgrades. I use 510 ss cams, with. adj. lifters,new push rods, kn air cleaner and samson slip ons. Kendal Johnsons team did the dyno and maping. I came out with 74 hp and 86 fp of torque. The increase in power is undeniable. The entire proceedure was around 1200 bucks. I feel it was worth the cost. Thanks to all the guys that responded to my questions prior to the work.
