I have an 08 with DPF/Cat delete, S&B air intake and SCT Livewire. I decided to run the extreme tune for about a week and see what kind of mileage I get and see how it runs. I noticed on the SCT I can monitor EGT's with the factory primary sensor. Now I know this isn't the same as an aftermarket probe in the manifold, but I'm wondering how accurate it is. I monitored it for the entire 180 mile trip this morning, with the cruise set on 71 (rpm's at 1900), and the EGT's never got higher than 850. The only thing I didn't like is the way the tranny shifted (I left it stock). I am leaning towards sending the SCT to IDP and have the custom tunes put on for the tranny and engine. My biggest concern is reliability. I want this truck to last a long time, but also want to get the best mileage possible. Well after that long drawn out statement, I guess what I'm really wondering is what is a safe range of EGT's with the primary factory sensor, and is it safe to run the IDP tunes as a daily driver? Thanks ahead of time for any input.:icon_ford:
