Dyno Correction Factor

[Dave Ratcliffe]

I was looking at my dyno charts the other day. One was stock and the other was after Phase II injectors. I've always thought my truck dyno'd low for a stock ETH @ 205. 7 hp and 285. 6 hp after the injectors. I just noticed the other day that a correction factor of 0. 93 was printed at the bottom. Would this make my corrected horsepower figures be 221. 2 and 307. 1?

A correction factor of 0. 93 means it is taking 7% away from your actual numbers. The correction factor is figured, then multiplied by the actual recorded numbers. 0. 93 is very low. Might check for a bad temp probe or pressure sensor on that dyno.
