Electric Water Pump

Looks like you hit 120 at about 5050-5100 RPM.. and you hit 5500 RPMS, almost 10% faster than 120.. (132)

I never did the math. What about 5,750 RPM?

Trying to be more accurate, I start-stop-start-stopped the video until right at 100 MPH. RPM was 4,750. What does that equate to at 5,600? 5,750? My math isn't working. I'm getting 115.18 MPH at 5,600. That ain't right.

@iamdub YOU NEED a PPV speedo!

I wanted one for a minute and I can find 'em near me. Besides having the mileage programmed, I'd have to have an overlay that doesn't say "CERTIFIED". Which, then, I'd want a full custom one and I'm too indecisive. Much easier to plug in HPT and log it. Or, just keep it under 120 like I really should be doing.

Here are my stock settings for a 2012 Z71 (4WD, 3.08)

Think I will tweak it some ... maybe over 4k RpM & 80% throttle? idk ...

IMMEDIATELY AFTER any Wide Open Throttle UpShift
- as in 1Up2, 2Up3, 3Up4, and if you're crazy, 4Up5 - what is the LOWEST the RpMs could drop down if you keep it floored?

Less-than-wild / sorta-educated guess assuming 6L80E:
right after 1Up2, RpMs fall to ≈3300RpM before they climb again.
(All the other gears are tighter.)
So, set AC shut off RpM to 3300RpM, or 3250RpM, so it stays OFF during a WOT run.

As for the TPS%, keep track of how you drive.
What's the highest TPS% you normally use that is NOT 100%?
My educated guess, over years of tuning IronBlock LT1s: 75%

These settings are not just for fun. Your AC compressor will last longer too.

110mph instead of 100mph at 4,750?
I'm showing 127mph@5,500 or 129mph@5,600

Trying to be more accurate, I start-stop-start-stopped the video until right at 100MpH.
RpM was 4750. What does that equate to at 5600RpM? 5750RpM? My math isn't working.
I'm getting 115.18MpH at 5,600RpM. That ain't right.

Did you try playing it back at 0.25 speed?

Didn't know that was possible. I'll be damned.

Thank you. I don't know what I was doing.
