Dinan didn't make any claims of performance gains for any mods unless combined with a tune. However, we know that more, colder air in almost always helps as long as the engine adjusts for proper air/fuel mixture so there is likely some benefit from the COI alone but without the other S level components my quesstimate is 6-7/1-2.
I haven't checked recently but transmission software has been available. For $300 it is a great performance investment. I have no idea how anyone today can get all the Dinan stuff to get to 369/382.

Brian so you like the Dinan trans software? I have been thinking about getting this for my X5. How does it differ from the stock feel?
