14 HP must be from the K&N sticker that came with it.

Before we get into busting myths here I would like to understand you correctly. So with a chip, coils, and 94 octane you dynoed at 227rwhp, then when you added the fipk you picked up an additional 14hp to bring it up to 241rwhp? Is that the way it happened??

Lastly were the 227 and 241 dyno runs done on the same day, or was it the 227 run today then the 241 run a week later??

Reason I am asking is there are soooooo many things than can contribute to a 14hp gain on the dyno unless the same dyno was used for both tests, motor and fluids temp was the same on both tests, and atmospheric conditions were the same on both tests. Even running back to back taking 30 min to swap intakes could skew the results. Lets say between the 227 pull and the 241 pull the temp and humidity outside dropped a few degrees and 5 % respectively, then in the 30 min you took to swap intakes the motor cooled down a bit. Well now you might have gotten 4hp out of the intake and the other 10 just because a change in conditions. Basicly to get an accurate result of PROVEN gain per mod you would have to have a vaccume chamber to put the dyno in so that atmospheric conditions are the same each time, you would also have to have sensors that could monitor all engine and fluid temps and keep them within +/- 3% of each other on every run, you would not be able to move the truck once it is strapped to the dyno as tightening it up a bit more or less could throw off the results to a degree.
