anyone running the 275 tune as a daily driver? and puking fixes?

[abruno25]

i'm running the 250 tune as my daily driver now and i want to go to the 275 as a daily driver to try and make up some mpg since i did my lift and 37's...
anyone have any insight on running the 275 for a daily driver?

I run it every day. Coolant level hasn't budged in 12,000 miles with updated head gaskets and stock head bolts.

was your truck a job 1, that you changed the head gaskets? also i think mine is a job 2, my bild date is 08/07. did u see any difference in mpg between the 250 and 275?

Yes, my truck is an early build Job 1. 8/07 is a Job 2. I see much better highway mileage with the 275 tune, and any roads that have a 45-50 mph speed limit I see better highway mileage. Anything under 35 mph is not much better than the 250 tune. Lock up being at 45 mph instead of 50 mph definitely makes the 275 a better tune for daily driving in my opinion. As long as you don't beat on it, you shouldn't have to worry about head gaskets blowing.

sounds good, are you running the tcm with the 275?

[08stroker250]

Yes, but I have about 35,000 miles without the TCM running the 275 tune as DD as well. My tranny is still holding up fine. I recommend it for guys who run the 275 and 310 tunes for competition use that have Job 1 TCM's, but for daily driving I do not recommend it.

That's a little too early to have a 6.4 in it...
