Long awaited on both ends. I installed the pcv on a cup bike here. The throttle stop has been removed. Couple pieces of data, initial data is bone stock out of crate(stop removed), stock air filter and lid, dB killer installed, with Akra map. Graph shows "stock" this bike vs fully tuned (with k&n air filter and lid mod). The other graph shows after the k&n air filter and lid mod (no tuning on a 0 map) vs tuned, strictly gains from tuning. All data is off the same bike, pump fuel, dB killer installed etc.. Only changes from as delivered is new filter, lid mod, and tuning. Rev Xtend is enabled to 10.5k. I can't wait to see what piston and cams do for it!
