Yea I'd freak out if the needle climbed that far as well. I normally have them shut it down between 3500-3800. On the 2nd dyno I got it on, I told the guy 3800 unless you see the back pressure gauge peg it at 100psi because we were still messing with that gates. First time I ran it on a dyno the gates didn't open at all and they made me dyno it, pegged the gauge x2.
