I just got a refurbished Diablo intune i3 on e-bay, for about $160 less than new. Loaded the 87 octane tune (you can keep stock tune and change other parameters like AFM etc), turned off DOD/AFM, increased throttle sensitivity 10%, firm shift trans tune. It did what I wanted it to do. I have absolutely HATED the AFM since day 1. I've been driving in M5 for over a year to avoid switching to 4 cylinder mode. I have my 6 speed trans back! I'm still considering a custom tune from DiabLew for driveability improvements. I too, do not want a race truck, just something that I enjoy driving. I'm getting close.
