so i adj it up pretty far, im a little iffy on taking it all the way out, is it very hard? i just dont wont to lose it into the pump, i noticed a little dif but not the big one i was looking for

when you stomp on the pedal from a dead stop there is a little bit of lag and a huge black cloud, i tired moving the afc housing back and forth and got the smoke to go away but still had the lag and alot less power, before when all i had was a plate i could hit 30 psi as soon as i stomp on it, maybe its just cause im running alot more fuel and bigger turbo now??? all my friends that drive diesel like powerjokes and dont know **** about cummins so i have no one to really compare it to

I took the screw out while I had the pump out, to make sure I did not drop it.

with a bigger charger comes some lag, and over fueling it on the low end will also give yo lag.

everything sounds normal to me, just need to fool with the afc to tune her in

I'm running a #100 plate on the street, but will probably pull the plate on weekends at the track. Can I leave the arm adjustment alone? Also, I ground the front of the plate so I can slide it all the way forward and still get the afc housing on. With that extra travel is it even worth pulling the plate for the track?

you can leave the arm where it is, the beniflt of having the arm all the way up is it rides on the afc till it bottoms out.

if your getting full rack with the plate in there there will be no gain when you take it out.
