Default Help?? Please?? AFC

I put a #8 fuel plate, adjustable boost elbow, gauges, and moved the afc all the way forward. More power at low speed, but falls on its face at 2100. Can not make more than 18 lbs of boost. Have not moved smoke screw. Boost elbow put on turbo. Please what am i doing wrong?? Or what am i missing?? Thanks to all here a great site!!!

Mike

To add to their suggestions i would say if you dont plan on going with 4k's buy them anyway because eventually you will want them.

Diesel performance accessories for Dodge Cummins, Ford Powerstroke, Chevy Duramax has 4k kits for good price and comes with instructions on how to do it is very easy u just have to be carefull not to drop anything in your pump bc pulling it off to get it out will suck and it makes it easyer with a magnet
