A8 transmission shifting problem 1-2 and 2-3

[SSDION]

I have a C7 Z06 A8 2015 with some bots-on (AFE cold air, ARH headers, Lower Pulley +15%, meth kit, bigger rear drags radials and a tune) At part throttle transmission is shifting very well but at WOT shit 1-2 and 2-3 transmission do not shift when required. Shift 3-4 and 4-5 are fine and firm.
DESCRIPTION OF WHAT HAPPEN: Car accelerate over MPH and engine RPM programed. Engine rpm raise to limiter, throttle close, spark become negative, car slow down some mph AFTER AN ETERNITY, car shift, throttle reopen, and spark raise and re-accelerate.
I did use HPT to do some changes:
1. MAF calibration
2. POWER ENRICHMENT adjust
3. Reprogram with gear/tire wizard
4. reduce shift RPM (part throttle and full throttle)Normal-A-B
5. reduce shift speed (part throttle and full throttle) Normal-A-B
6. raise shift pressure
7. raise shift inertia
8. reduce shift time
9. raise Trans default torque limits
10. Raise engine peak torque, delivered torque max?..
11. play with Driver demand tables (up or down lines 74-86-100)
12. adjust some spark tables
I am a beginner tuner, I do tuning only on my car and I really need a help! I do not know if I made some change in ECM or TCM that generate my problem. Is this a result of torque management or some conflicts between tables?
What the experts tuners think about my problem and how to log data and resolve my problem. Can you refer me to some thread about this subject? THANKS

Did anybody have work and resolve a similar problem on A8 transmission?

Post your tune and a log with your problem!

[luisdavid11]

have you raised the max pressure allowed

[SSDION]

have you raised the max pressure allowed

I DID RAISE MAX SHIFT PRESSURE ON TRANSMISSION. from 110 to 220 psi and base shift pressure TCC ON increase 35 psi in first-second and third gear with no positive result.

Post your tune and a log with your problem!

I have add log

[luisdavid11]

Post tune.

its more than likely in the shift mph. Post the tune

[SSDION]

its more than likely in the shift mph. Post the tune

I have added tune post 1

bump this up

I have try 150 psi and 200 psi with no change in transmission shift.

Did you get the WOT shift 1-2 and 2-3 figured out?

[SSDION]

No solution for now. My car is stored for the winter. I do have a smal list of things to try later this spring and I am open to add some sugestions from people who have similar problems and ideas.
Thanks for helping me

What do you want to see in order to help me?

You ever get it figured out?

Your issue is simple. You're not commanding the shift early enough. Drop the MPH way down. 6L and 8L trans shift based upon MPH. I tune alot of these 8L90s and rarely have an issue, ensure your tire size is correct as well.

Also, Looked at your tune, it needs a ton of work.

You are also commanding shift times that no transmission is capable of doing so, although it will try.
I would also make sure you're reporting proper torque, and your TB isn't closing.
