Tuning 6.0 and longevity

Good. Its tuned mostly by me as an email tune was just not cutting it.  Like any other 6 liter I have owned in the last decade I run premium and advance the hell out of the timing from stock and what a surprise.... it has way more power lol. I tried playing with cam timing but it wasn't loving it and frankly the e78 ecm in these trucks is a lame duck to deal with.  That said the gains are still there for anyone and even just playing with the shifting makes it feel night and day.  I don't agree with the "leave it stock" statement as they aren't going to live any longer for the average guy and it's way more fun having something that isn't such a sack like the stock settings give you.  It's the same logic that drives complaints their truck is undergeared that I used to commonly read but no one ever rectifies the situation. I did that as well as my truck has 4.56s in it from the stock 3.73s. That also made a massive difference in drivability. 

 

Oh and for fun if I drive my truck gentle... leveled with 295/60/20s and the 4.56s still returns in the 15 mpg mark lol.  I don't complain about my fuel economy.

your 6.0 didnt have 4.10s in it?

Sure didn't. Would have swapped it if it was 4.10 anyway... still undergeared.

Sent in my files to Blackbear on Thursday. Hopefully get my tune in coming week. I will let you know.

Did you get tuned?

[Paulismydog]

I did. So far I am underwhelmed. Shifting marginally better but seemed to lose 2mpg. I made a new data log and sent in. Hoping Justin can tweak it for the better. If not I will go back to stock for the mpg gain.

Well thats not what I expected to hear, keep me updated. I am on the fence about doing this but already get such poor MPG I can have it get any lower.

Will do. I am optimistic he can work things out. But it's a pretty slow turnaround. Frustrating.

That's a tuner issue lol...  why I end up tuning my own trucks.  That said if you request to stay on 87 octane the gains will be underwhelming.
