2018 F-350 light weight tune review

[heranney76]

Hello long time reader messed with a few and learning as i go. we have a previous weight reduced 2018 F-350 C&C truck. I messed around with the tune on it helped alot but still lacking on top end. Tuning helped take off and shifting tremendously reduced flares and tc shutter it had previously. I was hoping someone could point me in the right direction some things to tweak on. Truck was boggy and slow with original file. Thanks in advance!

The Fuel temp sensor under main injection looks out of sorts to everything ive saw and read about before if anyone has any ideas

That tune is setup for shift on the fly which is why the fuel temp sensor tables are out of sorts. Are you using the switch or is your actual fuel temp sensor plugged in next to engine mounted fuel filter?

I'm still learning to tune my own powerstroke, but it looks like some of your boost tables are still stock and you might gain some top end if you add more boost in the higher rpm area.

Here's a stock read off a 2019 F350 I got a few days ago for you to compare.

It's plugged in not using a switch. Doesn't look like it's ever had a 5 position switch. The sensor is plugged in but when I looked at adjusting them to match what I had seen here and a stock read the mv on the sensor were all out of whack.
