Darreli & FirstSHO were actually the 1st two to have LMS tune their cars with the upgraded turbos.
They upgraded using the Tial Turbo Upgrades.
It took (at that time) quite a bit of time to "dial 'em in" so to speak.
I don't see either of them post up much anymore. So not sure if they'll chime in on this subject matter (or not).
Dan has made significant strides since then, so I can't imagine it taking him as long as you've been quoted.
I will find out 1st hand as I have an appt scheduled for the last week in February.
As far as I am aware, my car will be their first crack at tuning with the ATP Turbo Upgrades.
I'll letcha know
