I have never had a stock truck with gauges but I just put this cheap digital egt gaug/probe in and it seems like temps should be higher than they are.


First start idle was about 165* after a minute or so and then I stomped on it after I got the coolant up to temp and it took nearly a full throttle run to 70 to get up to 800*. The only mods to engine are stock plate slid forward and star wheel turned a few clicks. Ive slid the afc housing forward but backed the smoke screw out so smoke is at a minimum without the truck being a dog. Normal driving temps seemed right at around 650-700* and idle when I pulled back in the drive was around 450*, I let it cool to 330* before shutting down. I was expecting to hit 1000* or so with the hard pull, does this sound normal?

They might be accurate. I know on my 05 running my tow tune I hard a hard time breaking 1050° empty, but could break 1200° towing. 


So empty on a stock 12V tune may just not run that hot empty. 


That being said... $20 for a probe and gauge seems a little cheap, and I might not trust it. 


Wait til morning and see if it reads close to the ambient temp.

I am close to stock, DDP 50 hp injectors is all. Your cool down seems hot, I can come in off the hwy at 800 and it will idle down to 250 in less than 1 min. Now pulling is a lot different.

Lower timing = lower egt’s?


Higher timing = Lower EGT's


At least on my 24V I'm running 26° of timing at 2,000 RPM in cruise state. Making in the 20 to 22 MPG now. There is other things like my pop pressure is up at 320 bar so I need more timing for the late injectors.


Being you've got a P-pump you are going to get very experienced in setting timing being that is the key factor to good MPG




NOTE: -50°F for the pyro to be right with my ISSPro Gauge then +1 MPH to right with my GPS.
