Default MS3 Cam only tune

Recently picked up a car with a MS3 cam, aftermarket intake, headers, and stall. I took the car to the track last night and hooked a 1.66 60' but only ran a 12.15 @ 111 mph. I bought HP tuners when I bought the car and started looking at the tune and noticed that the car shift points are really low for a cam this big. The 1-2 is set at 6300, 2-3 at 6100. If I move the shift points to where they should be (I'm thinking high 6's), do you guys think I'll pick up the few tenths and 5+ mph I think the car should be running? I've attached a log of the pass and the tune. The log of the pass starts around the 2:30 mark of the file.

I wish i could give you some info on what to do to make the car faster but i did what the scan. AT 1:27 your KR from what i see goes up to 4 then back to nothing.
Not sure but i dont think that is good. Maybe an experienced tuner will chime in about it. Sorry, just thought a heads up is better than not realizing just in case something is going bad.

I believe the KR at 1:27 was from when I did my burnout and the y-pipe banged against the floorboard.

Those cams love shifts at 6700-6900
Raise the shift points and up the shift pressure. If the transmission is good it will improve for sure

I have a similar cam and found that every 300 rpm increase in shift up to 6900 reduced my ET by 1/10th. Shifts at 7000 made no improvement over 6900.
