Start searching the posts...you're right, it's hard to find one that hasn't at least had a drag pack or seats etc taken out 12.1-12.2 @ 115-118 seem to be what the fast ones are running

At the tires?

Waiting for the NA guys to run turbo guards

I wouldn't trust ChatGPT...

Would like to see them log stuff like MAF flow, spark advance, etc on those runs

When you mention jerking around, I wonder if your issue was due to the clutch or the tune. The supercharger shouldn't really factor into the way the car drives unless you are past 3/4 throttle.

And I want to see before and after datalogs from the car, showing the knock with gas from one station, not showing it with gas from station 2, and then putting gas from station 1 back in... Gas is the first thing to be blamed for any car problem when it's almost never the case.

Why did you hate your 2016? A 6 speed with a Whipple should be plenty of fun Just read the fine print, if you blow the transmission they are only going to cover $2,000, which is BS because it'll probably cost that much to just remove and re-install it!

there are many forums other than this one... google "Costco gas knock" and see what comes up...

again, "top tier" just means it has a certain detergent package Costco has has had a bad reputation on the forums for years, especially with supercharged cars

F150 isn't the same engine or programming....

Should be getting an oil change by now anyway

No, but a lot of people have found certain brands of gas "93" to show knock on their cars when others don't I know I am getting decent gas from either Sunoco or Mobil so that's the only places I get it from. I don't have a Costco membership but I don't get gas from Kroger or Speedway.

You said you don't have to be careful with Costco gas. But you should still make sure it's performing like the octane you're expecting out of it.

Top Tier sticker just means it has a qualifying detergent blend. It doesn't mean anything about the octane. It only tests for deposits. I can't see how the previous poster's gas gauge failure was nothing more than coincidence, though.
