I have a 97 cummins with a turbo back 4inch straight pipe. it is a work truck that pulls at the most 19k IBS. i dont kno what fuel plate to add or just to take it out. I like my trucks to blow smoke and have LOTS of power but still get good MPG and still be reliable and not break. Please let me kno what to do.

 

i hear a #10 plate is a real nice one for what you want to do

 

You need gauges, at the least EGT, BEFORE making any fuel changes. You can easily melt the pistons and/or turbo. That wouldn't be reliable!
Smoke is unused/wasted fuel. Think of it as mileage going out the pipe.

 

Gauges, then a #10

 

How important are the gauges? If i ran without them for a few months and got an aftermarket fuel plate would it mess n e thing up for a few months?

 

Not worth risking.

 

Gauges should be the first thing you put in imo. Egt, boost and trans temp if you run a auto.

and has the kdp(killer dowel pin) been dealt with?
