Other platforms are not this platform. What works for one might not work for another.
Seems like on the other applications of ITBs on other platforms they saw gains because the stock manifold and or throttle body did not flow sufficient enough (ours already does)
or they are running with trumpets or very short runners, which again seems like it is just changing to shorter runners for shifting the power band up.
I’m just trying to see and understand the theory or physics behind why going from one throttle body (already bigger then needed) to four individual TBs would inherently in and of itself even when “tuned properly” would give any benefit other then sound and maybe initial throttle response.
