OP, listen to Pray he is giving you the scoop. If ARH LTs with tune only gives you 15 RWHP then shorties might at best give 1/3 of that with a tune or less. Save your $$.
Maybe DA helped some, but a big part of Prays times is due to he can drive. Check out his 60'. Seat time is one of the best mods, it is fun and almost free.
Also I agree the MSD is not so good on an A8, but on an M6 with a 6,800 rev limiter it is not so bad although it scares me a bit. And E85 can then fatten up that curve some. Looking forward to see what a ported MSD can do.
Looks like crap?
