Mustang Dyno vs. DynoJet Dyno on a Stage 2 TT
I have a Stage 2 TT that has GIAC flush, EVO intake, Caragraphic exhaust, and RWD conversion. I got a dyno last Saturday done on a Mustang dyno over in Torrance. The car ran peak HP @ 397rwhp and peak TQ @ 425rwtq in 4th gear, but I was not able to get an AFR graph (temp in the low 60s).
Today I got a dyno on a DynoJet dyno over in Irvine. The car ran peak HP @ 462rwhp but with no torque as they didn't have the time to took into the coilpacks (dyno was HP vs. Speed) in 4th gear with temps in the mid 60s and the car ran RICH around 10:1 in the middle of the runs and then leaned out to around 12:1 at the end of the runs.
So it looks like the difference between the Mustang dyno vs. DynoJet dyno is approx. 15%. I'll post up both dyno sheets on Monday.

Yeah, I have the K16s with a GIAC flash...now that I have two baseline dynos it's time to make a decision on which software to go with for my hybrids...

I never did dyno the car when it was AWD. And yes, it was the first time that I ever dynoed the car on either of the two dynos.

I own a Mustang myself and we often see a few % variation against other dynos exactly like ours.
Bottom line, dyno's are used to measure gains or losses, not absolute power. Get your baseline at the dyno shop you feel most comfortable dealing with....mod away and measure your % gains.
If I remember correctly the weight and hp@50 used at your guys dyno day was incorrect. This in is self could lead to difference between the 2 dynos.

Brother...that's dynos, period. I've seen a 40 whp difference between MUSTANG dynos that were only 40 miles apart.
Not to mention the huge variences I've personally witnessed between DynoJets, Dyno-Dynamics, Dyna-Packs, etc..
This is exactly why I trust 1/4 mile Trap Speed more than anything else to tell how much power I'm really putting to the ground.

Were the weather conditions similar?
