Installed 80 mm throttle body on my SL 55

I just completed the 80 mm TB mod. My first impressions are that the little monster pulls harder than before and the increased throttle response is noticable. The car idles about 200 revs higher than before and it takes almost no pressure on the throttle to maintain freeway speeds. I am running an ECU upgrade from Renntech. Do you think the ECU will adapt to the bigger TB and drop the idle speed and also allow for a bit more throttle at freeway speeds or do I need to have the ECU remapped?

My list of mods are: Renntech package plus (pulley, heat exchanger, IC pump and ECU upgrade), EvoSport ceramic headers, larger plug wires, phenolic intake spacers and VRP 80mm TB.

Thanks guys
