I had three 4.0 tfsi engines, two in the RS7 (14 and 17) and the Bentley GT3R. Dont expect that same margin gains from the RC on the F90 since you are starting at a higher number and the RC is a more safe/conservative/non dyno sheet selling piggy.
I like to think equate hp/tq gains to dollars spent, at times and the RC is one of the better SAFE bangs for the buck.
