I had the same issues when i did a sneaky trip to Santa Pod at the end of October after we had all been to shakey. I used launch control on all my runs, but had no grip whats so ever, quickest time i got was a 12.64 @ 113mph, the other runs were bad compared to my normal low 12s, 13.85, 13.62 and the last run i gave up 15.11 
However i raced on Sunday at North Weald, grip for the first part was really quite good considering its concreate, 1st run was a 12.27 @ 112mph, i didnt use launch control once this meet, i think having it set at 5800rpm is too high.
I had another 6 runs up the strip, and managed another PB by the slightest of margins LOL 12.13 @ 113mp i did that twice, also ran 12.19 @ 113mph twice, the sun went in, traction became a bit of an issue so i dropped to a 12.41 @ 113mph. We had a quite heavy crosswind all day, but nothing that caused too many issues. My last run, i didnt get any grip off the line, so cruised up the strip like i was driving Miss Daisy. 15.24 @ 72mph. Terminals came back down to 113mph where last time i managed somehow to get a 120mph terminal
Tailwind possibly ??
I also had the pleasure of racing a GTR 35
as i wanted to see what the difference was between my potentially outgoing car to the potentially incoming GTR. I enjoyed the race hugely
I honestly dont think that the car is capable of a high 11 in its current tune, i know its only 0.13 but i consistently keep posting low 12s ( which is a very good time ) if i do choose to keep the car, then i can see maybe another little enhancement coming, that i have dealt with before and may look to employ to do the job again to get me in the 11s
