Well I was messing around with the 3865 Tuner and I played with the idle adjust that they have. You can adjust between 800 and 1600 rpms. Its kinda cool. I was kinda shocked though at the 1600 rpm limit. I mean yeah I can see why you'd want the 1600 rpm idle for drag racing... but street use? lol That seems kinda high. Damn...

 

the new updates for the 3815 tuner have the same idle control, kinda neat feature
