Error code: P2119

So are you getting these codes when on the "stock tune" or on the Trifecta tune (stock or perf mode)?
It sounds like its happening while tuned And then you flash back to stock. If that's the case i'd try driving around on the stock tune for awhile and if you don't get a CEL then its a tune issue.

If it comes on either way then idk. Possibly the gas but I doubt it. Vacuum reference lines followed by wastegate could be the culprit. Either way it's a bummer and sounds like you need a new dealer, they don't sound too big into diagnostics, just going where the scanner tells them too.

Ok, it's tuned right now and on power tune mode with full tank of 93 octane, no code whatsoever, BUT still buckles\shudders some times when I floor it. I'm hoping this is just the leftover 87octane that's causing it.

Does the car have to relearn what gas is currently in the tank? After this tank of gas and it still continues buckling at WOT, I send Vince a data log.

check your spark plug gaps.

Good call!

check your spark plug gaps.

Was there a guide on checking the spark plug gap and everything that would be needed on here somewhere. I did a search but no luck.

thanks

remove coil cover. remove coil pack with Allen wrench. remove spark plugs with a 5/8 socket. a magnetic retrieval tool helps pull them out. use a spark plug gap tool and set them to .028.
