For instance, if your max MFD is 100 and it gets you a certain PW at a certain RPM/ICP, then increasing the MFD to 110 or higher will allow the PCM to calculate (using RPM/ICP) what the new, higher pulse width should be. It's a way to get the popping and stuttering that you hear in a lot of sled pulling videos too.

What do these numbers actually represent? The MFD map represents mg/stroke per injection event. It's a direct quantity.


Ohh boy........7 on 7.....that stuff will sneak up on you.......lots of stories started with that drink. You're telling me....I made 6 of them last night and drank them in about a half an hour. I slept good last night. I'd been awake for 31 hours since I couldn't sleep the night before.
Hope this info helps a bit.
