I wondered this myself and if my tranny would behave I'd try 6750 or whatever RPM was needed to not breech 6750.

If you have DMRs enabled you could plug your torque curve into this calculator.

I ran a few different dynos and the results were the same showing the stark differences between PP/nonPP.

Whether this holds up in the real world, IDK, maybe the MKS will behave better so I can test it at the track.

It dried enough to make some runs into 3rd.  I will check the logs and post them in a bit (ice cream run).. 

There was definitely more wheel spin/hop on engaging 2nd.   But there was also a scary 'blip' where it either spun the tire again or the fuel cut. 

Logs will tell..

Logs... I could not tell if there was a fuel issue or it spun the tire halfway through second.. but it definitely had a power interruption for less than 250ms

The shift to 2nd is hooking up at a reported 4200rpm. So thats better but i would like to try for 4000.. 
The shift to third hooks up at 4000 +/- 50 rpm so that's awesome...

gear changes are happening at 31mph avg and 52.5 avg ..

Yet the time in LiveLink shows faster 0-60 for the 1st test,  but slower for the next 3 .. that baffles me.  Were shifting into much better TQ curve.  hmpf .. research time.

maybe i will make a run to 105 when i can and check that time.

scratch that.. i'm going to drive it another day and retest.

Crap, just realized I'm going from the 3.16 to the 2.77 final.

Complaining about improvement?

I prefer the 3.16

What you really want is a 3.73, admit it

[TopherSho]

well, that was fun.. yet perplexing.

it appears the TINY loss of HP negates the lower rpm and TQ range.  It is posting the same 0-60 as before .. despite shifting 500+ rpm early.

All things considered i will leave it there for now since it is NOT impacting performance when shifting sooner.

hrmpf...

Need to test 0-100 next but conditions were not good for that today.

What are you getting 0-60? And are you break boosting or just mashing the gas? (On my phone, can't look at the log)

Just got done reading his logs from an earlier post. No brake boost(1100 rpm) netted high 4's low 5's on the 0-60. This was shifting around 5900 rpms. Can't seem to view the latest .zip file of logs he posted tho

Just opened the file, no issues.
