My friend has a 93 cummins automatic. so far I put gauges, air Intake, 4" exhaust after stock down pipe, and some New Era 370's 80hp sticks. Oh and I turned the torx screw in 2 turns on the top of the pump under the cap on the afc. It didnt help it much at all and im guessing that the pump needs to be turned up to get the hp out of the injectors. This is the first time ive messed with a first gen so I need help, what to do, what to watch for and so on.

There is a pinned topic at the top of the 1st gen page. Click there and read away. Tell ya all ya need to know about turning up these beasts.

 

The tiny torx screw is the "smoke" screw check this https://www.dieseltruckresource.com/...601#post995601 out it will tell you everything you want to know about the first gen pumps.

Hope this help and have FUN

The adjustments are very conservative on that page.
