Hello All,
New to this forum, was on the E36 M3 forum but I sold that a while back and now I'm here! anyhow, I'm purchasing an '04 330i ZHP this weekend, wondering if you guys had any input on the Dinan ECU flash/Stage 1 software? I see the hp/tq gain is very minimal, but I hear it really helps bottom end torque, throttle response, etc. Is it worth the $300?
