I put on SE CNC heads, SE intake cams, R/t, and air filter. Came out with 118.3 and 76.9. I believe the tech did the dyno with the filter off to boost numbers because after putting on the V & H 2-1, I ended up with 109.9 and 72.6. However, I picked up a bunch in the low and mid range, and have gone from needing gas at around 120 miles to about 150. Same dyno, just different tech.
