For perspective, Dinan claims their CAI adds +14 Hp with their Stage 3 tune, +12 with Stage 2, +9 with Stage 1, and +5 with a stock tune.
I know people have dyno'd bigger gains than these, but I expect the proportions are pretty accurate.
...adding: I guess the Dinan Stage 1 tune is comparable to stock 1M.
