Changing the spark plugs.....

My car used to routinely invoke the ASR as I passed through 5500 rpm, as the tires would begin to break loose.

To confirm you could replicate it with ASR off, but I do not really recommend that.

Perhaps your new secondaries, plugs, etc, are now providing you with a lot more power than before.

Try lighting them up during launch, and see if the pushback that you will feel on the accelerator is the same.

If so, it's a good thing!

You are making too much power for the tires!

You know Marty, Yun and you are right on about the ASR. Before when approaching the 7000+rpm shifts during WOT, I never felt the ASR engage.
Now since the secondaries are operational, I noticed the Z gets really loose at that 5500 rpm range , and even more so now with the new spark plugs. And of course already having Marc's chip in there with that extra 10 HP in addition to the parameters it enhances, my LT5 just runs sooooo good!!!
Yes, I agree I am making too much power for the tires....
