Being its supercharged I would expect to get a little more in the first half of the track.
10 psi of boost "may" be to much for the OEM compression on pump gas unless you have alcohol injection or running race gas. One of the biggest reasons for poor performance on a blowned engine is to much boost, so I would see if your getting any detonation, etc. before you destroy the motor.

If my tuner can't get me where I want to be, a trip to Jersey in the spring doesn't sound so bad

Are you holding the 10 psi throughout the entire pass? On my supercharged car I would occasionally have an issue with the coupler getting loose and bleeding off boost right at the discharge pipe bc it was very hard for me to get my hands in there and get the hose clamp really tight.

I talked to my tuner and we are going to log some runs after the holidays. 121 just doesn't seem right.

No, my local tuner did it for me.
I knew running on the stock runflats would hurt my e.t., but I did not think it would effect my MPH that much.
Here is how the time slips broke down:
Stock--- S/Ced
60'--- 2.089 --- 2.074
330'--- 5.488 --- 5.186
1/8 --- 8.254 --- 7.747
MPH --- 89.26 --- 96.68
1000 -- 10.602 --- 9.932
1/4 --- 12.559 --- 11.783
MPH --- 115.45 --- 121.65

You'll pick-up .5 easy with a decent set of tires right there.
I'm gonna venture to say the loss of traction and inability to launch at a decent rpm is killing your et and mph. Not to mention the rf's are more than likely spinning near/at the top of the power band as well.
