How we increased power without voiding H-D warranty

Who doesn't want to increase their power? It isn't very difficult to do these days but we have to be very careful if we want to keep our Harley-Davidson warranty!


We took our 2019 Road Glide Special into the shop to add more power... increasing horsepower & increasing torque!


We added a 55mm intake manifold before we tuned her on the DynoJet! Combination of Stage 2 & mods are below: Mods done from the start…..

* Mk 4.5 s&s mufflers 1801-1077

* Screamin' eagle torque cam kit #92500074

* Screamin' eagle extreme flow air cleaner #29400357

* Screamin' eagle pro street tuner #41000008c

* Screamin' eagle smart tune pro #41000445


Next step was…

* Screamin’ eagle extreme flow 55mm intake manifold #27300167

* After install we did smart tune pro learn with the dyno bringing the combination together for the end result!!!! *Stock numbers at the rear wheel which coincide with the final dyno sheet which also shows rear wheel measurements

* HP. 105 *TQ 118

* Stock hp 82 * Stock tq 107

Results on stock number may very some depending on bike!
