I have a 1994 7.3 idi turbo diesel and I am wanting to add power/speed to it, so what do you recommend because I can't find anything for my truck (i just need someone else's knowledge to help me), I do not want to touch the exhaust system.

 

First thing that you need to do is add a pyrometer.

After that, start reading up on how to tune/adjust your injection pump. Fuel screw, torque screw, timing adjustment. Those are the basics.

After that it gets harder.

 

Thier isn't a whole lot of power to be had ...
That said...add a pyrometer and look at the thread for making more power and how to turn up the injection pump ... Go small... Make adjustment in small adjustments as a little goes a long way....
