Not like the old days when the chevy was cold and just revved the motor to keep from shutting off and slammed into gear. Gone, no wonder that 350 turbo needed rebuilding.
If the dyno pulls are being done properly, you have to have either a dyno that also rotates the front tires....or the Star software from Mercedes that allows you to bypass the electronic "nanny".
without either of these, you an just do a dyno run to 4000-5000 RPM, not all the way to redline.
