High EGTs

[speedkills502]

Ok I never post, just read most of the time. I have a 2010 F250 H&S,S&B,5" sight pipe. I do not run it hard a lot just some quick bast and a burnout sometimes but it is a xl :shrug: single track it spins at wide open throttle if it is not above 45mph. I run it on the 250 tune and have it set to defuel at 45psi and 1450 on the egts. Today I come out of town and a dirtymaxx was on my bumper I stopped at a light and U-turned to go back to the shop. He followed me back up the 4 line. It was a kid he kicked it beside me at around 40mph so I kicked it it started to spin hard for about 50' and pulled away. I held it at wide open around a 1/8 mile and the alarm went of on the H&S it hit 1476 on the egt but I already had the maxx by 6 trucks. I lifted and the egts went right back down it runs around 600 at cruise 65mph it jumps over 1000 at wide open in just a few seconds. This my be normal but in most of the post I read this is high. Don't get me wrong it is a sleeper runs like a beast.

That's not bad for egts. I'd say def normal.

That is completely normal egt's. No worries.

Yup, mine defuels all the time with shinanagins as well.

Back when I ran H&S files I noticed significantly higher EGTs running the 250 tune compared to the HD300. The 300 ran cooler. With that said, I had my defuel set at 1550 degrees back then and I used to hit that during a hard run.

I dont even really look at egts if it is just a short blast. Be more worried about them towing a steep grade or that for a sustained amount of time.

Thanks guys just checking that is good to hear. Would you run the 300 tune with no head studs. I don't run it hard if it is not warm at 180 are higher.

If you have the means or money to get studs installed, then go for it. If you dont want to have to do studs when the truck decides its time to do them, then dont.

I ran the HD300 for months before I did studs. My buddy is still running it months later without studs. There's no real definitive answer as to what power level is safe. There's so many variables.
