How did I dyno this high? (not that I am complaining)

No roller dyno is 100% accurate. The only number anyone should be concerned with are the gains. What's to say most dyno's read low. It doesn't matter. It's not like

It's not like the OP was comparing this to other dyno's and bragging about it. Dyno's are only tools to track your progress and figure out if your mods actually show gains.

Yeah PM's tend to read on the high side, but I really don't understand why people get so pissy about seeing a high number. A 10hp gain is pretty accurate for an UpRev tune.

Exacty. A 10hp gain is a 10hp gain no matter what dyno you're on...that seems to be the average gains from an UpRev tune. Matt, take this to the track and see what your Z can do. If Chuck's car dynoed around the same as yours, you should have a 12 second Z on your hands

Realistically, the percentage gain is more relevant. And you hope they don't change parameters between runs.

Oh you will see me bragging if I run 12s lol.

I figured it was a bit high but I know they didn't change parameters between runs because I watched the screen through all the runs. They have a solid reputation and that sort of stuff would def show through.

While I'd like a universal standard I'm sure most of us with the standard boltons are within 5-10hp of each other so what is the true difference.

It was a fun experience regardless and the uprev was def worth it.

For what it's worth.... my gain from baseline with an UpRev tune was 25whp. Nice to see, but I was more interested in the torque plot over an RPM range. The whp number really meant nothing to me. Besides, who drives their car at 7500 rpm all the time?

Wouldn't that notion apply to the torque curve numbers also?
