Anyone alter their DFCO settings to bring in DFCO with the smaller amount of vacuum produced by the bigger cam. Stock the DFCO is set to come on with MAP<18. I'd like to change this to ~30-35Kpa..
Anyone see any issues with this.. Normally I wouldn't worry but as I'm driving this cammed car 130mi a day I'd like to maximize the fuel economy as much as possible(23mpg currently).
Oh yea, its currently OLSD
I move mine up to to around 40-45 kpa. Works great. Do you have a loose converter?

6spd car. Ok these next few days I'm going to play with it a little and see what kind of results I can get.
I just don't want it messing with my AFR in certain regions were the car tended to buck until I ramped the AFR down to 13.8:1 to eliminate the bucking.
