I couldn't figure out how to PM ya

What I meant is from what I understand a dyno is most accurate over a pull of 3000 to 4000 rpms and easiest to setup for. So generally our engines work from idle to peak+ hp rpm somewhere into 4500-6500+ rpms so they tend to dyno the top 3000-4000 or so rpms or "favour the top end".

If thats wrong fair enough.

So you do want to muck up the thread! You’re a real piece of work.
You got busted and that’s the end of it.
Anything else you’d just trying to cover up your lie and/or lack of knowledge and flip blame.

Just simply STFU & go away.

It’s amazing how much of an *** you are.
