I tried to dyno my 2010 SS this weekend with no luck. Stabilitrak kept stopping us from continuing with error codes, etc. Did the "7 second" hold to "disable" the system with no luck. Also tried abs turned off. Also tried competitive mode. Anyone else come across this issue? Is there a fuse that needs to be pulled?! Thanks-

When I dyno'd mine the instrument panel lite up like a Christmas tree. Thats normal. Just your cars computer thinking that something is wrong because your car is hauling a$$ and the front tires are setting still. Once the ECM gets back on the road it will re-read it and everything will go back off. hope this helps.

Right - I'm used to the lights coming on, and they did clear once I drove it down the block. The issue is that it is physically limiting power and speed to about 40mph, I believe. It's going into a safety mode.

Redline Performance, LLC in Arlington. Nice guys, and they did try their best to reconcile the issue. I'll be going to 21st century in Addison from now on though.

Issue resolved - idk what the Arlington shop was doing wrong but the guys at 21st Century Muscle Cars in Addison did it right! I'll post the official numbers in the appropriate thread.

Did you turn off the traction control on the dyno?

You may be throwing the codes for your front wheels. The vehicle doesnt understand why your rear wheels are spinning and your fronts are not.

If you clear the codes and its still on, Disconnect the postitive terminal from the battery for about 15-30 mintues to force everything to reset. Before you start the car after the reset, make sure all the codes are clear, and you should be good to go.

Sounds like they were using a pirated program or didn't keep up with their licence. If they don't pay HP for updates, they can't play.
