M@MRLS is 103dB, so you should be good as long as you're not signed up for the Friday Trackmasters track day (separate event).

Well, technically I asked a simple question, and I thought I was explaining more clearly, but obviously I am wrong.

I apologize.

Mobius, I suggest that you investigate the IncorporateAFR function as a potential tuning tool/enhancement. Use this forum and others to understand what it does, how it works and what changes will be required.

The margin is intended to place you on the rich side prior to autotuning. One of, if not the biggest advantages of the IncorporateAFR function is that it provides you with a VE table that is actually representative of the air pump efficiency. Fueling tables that do not utilize AFR target in the fueling equation have a tendency to mask errors. If the masked errors are in the offset portion of the equation (such as injector dead time), the initial scaling of VE with incorporateAFR prior to autotuning may back out some of the fuel that was added to compensate for these errors. There will also be errors introduced in the calculation due to rounding/significant figure limitations. Margining rich is the safe way to go IMO.

better?

I'll research this as I still do not understand what I need to do to recalculate my VE table to get it close-ish to what it should be and let autotune then work on it. I'm meeting with Curly tomorrow morning anyway for precisely this kind of stuff as well as a general going over of the car.

I'm confident my current as is ve table will be providing enough fuel, at least to 7-8psi.

Math doesn't scare me; I simply don't know it at the moment.

Patience, padowan. For now, revel in the multi-colored stock-wheeled glory.

I'm about 1-2 years before generation Z. and notice it. My sister is 3 years younger, and there is a difference.

Yes, I did. He called her his sister. That implies female in either physiology or self-referential psychology.

Don't SJW me or I'll beat you with my massive rolled up dyno sheet.

Bet you couldn't even get that sheet up hard enough to beat me with it. Big dyno sheets are for compensators.
