Madtuner and I have been disscussing this, he thinks it is the torque converter so we tried something.
I am attaching a transmission calibration for you to positively identify if this issue is torque converter related. The stock calibration in this file is your stock calibration. The custom "A" is the custom tune I sent you previously. The custom "B" tune disabled torque converter lockup entirely. Give it a try and see if you still get the surge. Once you're done testing, you can go back to the custom "A" calibration.
Using the B tune there was nothing wrong in 3rd gear, no feeling of a misfire or lack in performance, everything was fine. went back to A tune and the problem returned (incidentally the problem was there before the tune so its not the new tune)
So I presume I am heading for a bad torque converter? runs fine in auto and runs good in manual as long as I get out of 3rd before 4100, (I mean it doable it will go up to 6000 its just the 4100 to 5000 it has the slight sputter till you upshift ,bad for 0-60 time trial, and I do want performance free trouble

Madtuner sent me a file to disable the lockup just for that manual 3rd gear. Tested it an no issues with the 3rd gear
