90 spools reallyyyy slow after some work?
I installed a 4" DE exhaust with 4" DP on a 90 cummins 2wd 727 auto....i also put in a dennyT pin and adjusted throttle removed high idle screw etc.....
I backed the star wheel all the way out and smoke screw all the way out and it literally takes 3 seconds for it to spool it's VERY VERY slow....
Did i screw up with the AFC adjustments? do i need to put the starwheel and smoke screw down now? I was trying to clear up some smoke but i don't think the owner really cares. it spools so slow it's rediculous.
oh and i also swiss cheesed the airbox, like ALOT of big holes in it.
What should i do with the AFC? truck has stock turbo w/18.5cm
thanks

I had the starwheel out way too far. i was gonna try and clear up some low end smoke but i sacrificed alot of spooling. keep in mind this truck has a pretty old automatic in it too with 3.07's but i put the starwheel down almost all the way and put the smoke screw 1.5 turn down over stock.

Hum, not the same then. I turned the star wheel up and only lost more power, then I screwed it all the way down and up two. Got my power back but still have the lag. The smoke screw is at the top. I fabbed a spacer for the AFC to bring the fuel pin up higher. That helped some with the smoke.

turn the starwheel down farther, you're having the exact same problem i had. the starwheel has to be screwed down farther than stock.
basicly gotta give a steeper starting point on the fuel cone/pin
