I logged a 0-100mph run last night. I have my 1-2 shift set at 6750 and the 2-3 set at 6600. But on the logs its showing a 1-2 shift at 6450 and a 2-3 at 6400. Am I missing something?
My truck, 01 GMC Sierra C3, Heads, cam, intake, exhaust and a few other mods.

You will need to drop the shift MPH as well.

how far down do they need to go. They are about 6-7 mph lower than where Im shifting at.

You also need to set the Throttle Kickdown tables to 100% all across.

Here is the tune and log. The 0-100 is about half way through the log.

Ok, I bumped the MPH table to where it was shifting at, set the kickdown to 100% across the board. Went for a drive, and its shifting higher, but still about 100rpm low on the 1-2 and 150 low on the 2-3.

Lightly bump up both the WOT RPM shift and WOT MPH shift... then if you overshoot, bump one of them down a little.

Just an update.
Got the shift points and AFR straightened out.
Went to the track last month. Was 75 out and a DA around 5500+. Loaded the org tune and ran a 14.4@96. Got back to the pits and loaded my updated tune and ran a 14.05@97. I bumped the shift points another 50rpm and ran a 14.00@97.5. Pretty happy considering the heat. AIT started in the 115+ at the start of the run making my max timing 22*. Need some cooler weather.
Also, Im looking at doing a COS but I need the commercial version. I am using V1.2. Do I need to get the V1 Personal to the V1 Scan and tune?
