If anything the different power would come from the different valley plate and lifters. But youll find most of it is in the tune as a way to still entice people to the manuals which are seen as the more sporty version.
The valley plate and lifters don't vary between manuals and autos now - they're both the same L77 (saves dramas with keeping multiple engines in stock at Holden, now it's just one engine to R/R). It's in the tune and exhaust - the auto exhaust is very restrictive because people complain about "boom" when AFM is activated (they still do even with the stock exhaust).
