05gt mustang- tunning issue

[Rookie05gt]

I have 7140 predator, vr9r01 and 2005 mustang gt with Vortech HO, 9.5psi at WOT, bassani x-pipe and axle back, 420 rwh and 390trq at 6300rpm;
I have a custom tune in my car which is my only tune i have, i dont have a stock tune which i lost, my tune now is good and safe, but i cant advance the spark parameter any more, its all the way to the right, which, after taking it to the dyno, the spark is 14 or so. The air/F is 11.6 which is good, i dont want to change that. I just want to change my spark parameter, but i cant. Does this spark sound low? Dont know if one of my tuners locked it or because i have an old software....I want to completely reboot my predator with the lates stuff, than save my tuned(custom tune) as my stock tune, and go from there, but have my stock tune(custom tune) to fall back to, but i want to be able adjust all my parameters. Can this be done??? I have my DS dowloader ready and install, my usb-serial cable installed with the driver installed, what are the steps now???Thanks. Here is my tune, can anyone check it?

While I will strongly advise against adding any more timing to the car (there is a reason Vortech does not allow any more timing to be added, and thats so stuff does not blow up, you'll notice you can't lean it out either), your only real option here is a new custom tune.

Also, you cant lose the stock tune or the canned tunes, so they are all still there.
