In tuning both a carb and EFI on the DS I've noticed that the motor is VERY particular about the mid RPM jetting. I've found that the crispness of the acceleration can be dramatically changed by mid RPM jetting. The mid RPM jetting has the biggest effect on acceleration than the other jetting dose. If the mid RPM jetting is off a little, the torque suffers. The motor seems to like mid RPM jetting for best torque around Stoichiometric, which might seem lean from the point of view of maximum power.

 

Scooby that just went over my head, sorry but need more info. I'm not in your level of tuning? can you explain it for us in english, sorry but i'm stumped? I'm trying but I'm lost? Need more help!

I read it again & got it, sorry for the stupit question.
Later!

 

Stoichiometric is 14.7 to 1 air/fuel ratio!
