Could some tell me why i have that slump on my dyno between 4500 till 6000 rpm. Also why once i get to 8000 the increase is slow. I'm think the slump is because I still have my flies in but i may be wrong because I don't know it all when it come to Dyno.

Taking the flies out won't solve that problem.

Most likely the problem is in your Two Bro with Jice Box Pro. Disconnect them, and see what it does.

Since you lowered it and stretched it, I assume you are drag racing it?

Mine came down a bit at 4500 but was up at 5500.I have the flies out but at higher revs it doesn't matter.It climbs fast till 8 grand then dips a bit but is still climbing till 10200 peak at 175HP.But don't forget I have a Brocks full Alienhead with custom map.On the street at 8 grand it's really hittin and I mean explosive power.Check my dynorun here.

I also have a custom map with block off plates. Don't get me wrong she pull hard through the gears. I mean " you can't catch me hard" but I was just wondering was it something I could do to smooth out the line. I notice alot of guys dyno chart with smooth power line all the way to peak.
