lets just say over 400+ hp, 400+Tq...

Im not sure the dyno was right, there were a few cars with really low numbers...like a newer GTO, it put down a best of 260 rwhp...which I know is way low.

bottle, i had jets for 125rwhp in but it only added 80 hp!

Some of the jetting tune ups they give you are way rich and you will only get so much out of them till you lean out the fuel jet. Did you check Air/Fuel mix? This will tell you if the tune was rich or not. I used the NOS tune for 125hp shot once and only got 83rwhp, way rich on the A/F. Squared the fuel jets with NOS jets and got 118rwhp. Just a thought, but I know they tend to give very rich tune ups in the paper work. Rod

the jets were for 140+ motor HP and 125 rwhp...not 125 jets

This says that it was even more off. What were the jets? What was the spread?What was the bottle pressure?

Car sounded good, but I'm not sure I understand why we need to play the guessing game on its output.
