I had the Vanos upgrade done which wiped out my Dinan program.
Afterwards, it seemed like the car was not as rumbly but I just shrugged it off and thought it was my imagination.
Today I had the Dinan software re-programmed and to my surprise it is definitely louder and more resonant at lower rpm's.
Call me crazy but its true. I cant think of any explanation to this.
Im glad I went without it for a few days because I now realize that there is definitely a difference with the Dinan download done.
Better throttle response, smoother acceleration etc.
Did anyone else notice that the idle is slightly higher with the Dinan software? I like it a lot because it knocks less out of the hole.
