Hello, I have a 1987 6.9 idi and yesterday I was messing around and turned up the injector pump 3 flats. I was wondering if that was enough that I should get a pyrometer

 

touching the fuel screw at all without a pyro is risky business.especially if n/a.

 

Okay I already ordered one and its on its way

 

While you are waiting for the pyro I would recommend that you turn that back down so you don't melt a piston.

 

Okay I will it wasn't at all hard

 

If youre NA, half a flat is more than enough to get hot most of the time. Definately get a pyro. Do you have a turbo?

 

Okay. And no I don't

 

I did not drive it anywhere like tht just around the block and they after I was told tht I parked it and just turned it back down to where it is normally

 

Nate, which pyro did you get and from where?

 

I have no clue I just went online and got a cheap egt kit with probe and all

 

Just take it easy an watch your smoke, you will be fine until your Pyro comes.... EGT's are an issue if you hold them there for extended periods. As long as you aren't turning the day to night, and your coolant temps are staying decent, its not as big of a deal as people make it out to be.

 

Okay thank you very much this information has helped a lot

 

This. I turned mine up 3 flats, and unless you full throttle it with a lot of smoke, you won't hit 1200 degrees EGT. I got close with a full load up a good grade driving through Montana, but never hit it.

 

So I should be okay with 2 or 3 flats then???

 

still you need to put the pyro in so you know before it stops running, if you hold 1000 plus for an extended period of time, I use the 1200 mark as a governor, it can hurt the valves.
