I have a Fatboy injected with stage 1, V&H BSS and Thundermonsters as well. Still have the stock cams. My bike on the dyno pulled 78 tq and 75 hp with the Powercommander. Getting 3 to 5 more is not bad. How does it pull in the low end?

It's about 65 hp and tq on a true stock bike. when you add the stage 1 you gain about 10% more. I had the thundermonsters and the powercommander installed and has it dyno'd. brought it up even more. Right now my bike is undergoing a 95" stage 5 engine rebuild. When all is said and done, it will be 115 TQ and HP. Can't wait until spring!!!!!!!!!!!!!!!!!!!!!!!!!

I think it's a significant improvement over stock. Good job!

I got 75.5 HP & 87 TRQ with a Stage 1, V&H Classics, and SE 204 cams. I wasn't too thrilled at the time, but it was a noticeable improvement.

Stage One Harley-Davidson engines involve no internal changes made to the engine. All modifications are made by changing or modifications to external components on the engine. These components include air cleaners, carburetors, exhaust systems and ignition systems. No special tools or training is required to perform stage one modifications.

Stage Two Harley-Davidson engines involve any stage one changes plus changes to some internal "bolt-on" engine components. These "bolt-on" modifications include camshafts and milling of the heads to increase compression. Some special tools and knowledge of engines is required to perform stage two modifications.

Stage Three Harley-Davidson engines involve any change to any component in the engine. These modifications should only be performed by experienced mechanics with knowledge of performance modifications and engine "blue printing". Special tools are required to perform stage three modifications.

Stage Four Harley-Davidson engines are "anything goes". If it can be stuffed into a motorcycle chassis, it is worth trying. Time, expert knowledge, special tools and lots of money are required to build stage four engines. The ability to run on the street is not a criteria when designing these engines. These are all out race engines, designed for drag racing and other forms of competition.

I have the Stage I, HD slash cut slip-ons, SE 203 cams and a PC III USB. I got 75.5 HP and 85.02 torque. It would be interesting to compare the torque curves. Like you, I wasn't thrilled when I saw the numbers, but I was happy when I got it out on the raod.

Just an FYI on my 95" Stage 5 engine:

My local performance shop up here in NH is doing the work. They will replace the heads with high performance ported and polished heads that they make on sight. They will bore out the cylinders, install new pistons, cams, ignition, throttle body, adjustable pushrods, and cam bearings. They will dyno it and according to them, it will put out approx 115 tq and hp. They offer engine packages from stage 2 thru 4 as well. I will let you know what the results are when I get it back and run it.
