Help with Dyno numbers
I have an 07 C6/A6 z51 with paddle shifters. I've added the following mods: Halltech Stinger, Borla Sports axle back and a Predator perfomance tune. I had it dyno tested at the Funfest this past weekend, and had 3 pulls done. The temperature was in the high 80's. Here are the results:
Dynorun.003 Max Power=315.3 Max Torque=310.5
Dynorun.002 Max Power=317.3 Max Torque=311.1
Dynorun.001 Max Power=315.3 Max Torque=308.7
RPM=6.79 x 1000
I'm new at this dyno stuff so bare with me. But don't these numbers seem awfully low for a car with these mods? Tester said it was probably due to the temps. He figured flywheel hp was about 398, which I figure should be that stock. What could be wrong here?

What kind of dyno was it? I am guessing a mustang dyno perhaps? I had the same mods on my 06 C6 A6 a while back and I hit like 370rwhp and 363tq, and that was in the southern cali summer. I would definitly take it somewhere else to make sure everything is ok.
Post a dyno sheet if you have it.

. It was a Dynojet Research Inc dyno. The temp was 83 degrees, humidity was 48%. I use mobil 93 octane. I could feel the SOTP when I added Stinger and Predator. So I was kinda surprised at the numbers. But I will take it else where and see what happens. (I'll post dyno after I figure out how to do it.

Most LS2 A6's dyno around 330rwhp. Range from 320-340. So yes, these look a little low. You should see about 10-15 additional from the mods you have, but no more than that.
It's easy for dyno operators to make mistakes and come up with all kinds of funky stuff. Always research to find the best in your area.

Stock setup - Max Power = 329.4 Max Torque = Cant remember
Borla stinger & HallTech stinger - Max Power = 339.4 Max Torque = 344.6
I was thinking of doing the Predator perfomance tune also, but I know nothing about tunning, and know I would some how screw the Predator tune up if I did it, so I think that I will let LG Motorsports custom tune mine. 1hr and 30min away but I think the drive is worth it.
