I'm a bit curious if the average stock dyno numbers are very different between the A4 and an M6. I see one of the 3 GTOs with dyno results in this thread is an M6. What about the other two, or any thoughts on M6 vs A4? Curious as sometimes I hear an auto tranny saps more power, but dynos on the GTO do not seem to support that, possibly.
My M6 '05 put down 334 rwhp stock, but the tuning is pulling timing bad up top. I guess each car's stock tune isn't the same, or the CPU's are reacting to the different driving environment for each car/owner. Then, there's always the variances between dyno's. I'm looking forward to adding headers, cat-back and getting a dyno tune, but it would be interesting to see what a tune would get me before the other mods are added.
