No nose dives, but some bogs, and spinouts, along with one smelly clutch run. 
I think Chevy is protecting the ZL1 drive train. Is it any stouter than the standard SS? |
If you've had an ECM tune, the tuner may have programmed out the protection feature. Seems to me it's main purpose is to prevent warranty claims. If you've already voided the warranty with a tune there shouldn't be a problem.
Yes the ZL1 has beefier drive shaft and half-shafts at least. I think the diff might be stronger too. Still uses the TR-6060 tranny but it's the MJK variant instead of your MM6.
