I have seen some guys try and just split the throttle signal to a pair of TBs... does that really work?
My understanding with the HR 2nd throttle body is that it only opens mid rpms and higher (not open all the time). I believe I read this is done to preserve low throttle driveability but permit increased flow when needed. So it's not as simple as just having each throttle body mimick the other. I could be remembering incorrectly (or be misinformed).

He needs NOS!!!

It looks like the answer is yes, with a Haltech.
