How many HP and how much torque can I expect to gain after doing a Stage 1 upgrade?? I have a 06 UC. I installed SE one piece mufflers, Vance and Hines Dresser Duals, K&N RK 3909 AC and used a Fuel Pack to remap. I called the Vance and Hines tech info to ask for my specific set up and he told me to use the FP-0375 map. I love the sound. Exactly what I was looking for. Any input would be good to hear.

I did seach the forum and spent lots of time looking and never did find the answer I was looking for. lol..........

 

It's normally about a 10% increase..........or about a 6-7 increase. Most 88" stage 1 setups put the power around 72-74hp and 76-80tq......depending on how happy the dyno is.
