All good points Ron. Do what's fun for you period and tune out the noise. Works good for me
My 170 is at least a quart over filled with oil....very strange to me and it's triggering my OCD. I'm also seeing it PIG RICH on 93 octane and anything past about half throttle so there's that too.
Downloading the calibration does not void the warranty. No issues there and there'd be no way to tell anyway.
I have heard from very experienced people that preventing tire slip on the wheel does help the 60'. I used "high tack" gasket glue on my DRs on the Hellcat very effectively. They'd move a couple of inches a pass without it and almost zero with it. Prevents getting out of balance as well. Highly recommended:
