MPG Dropped Since Accident??? HELP!!

[Papa Rick]

My avg prior to accident was 5.2, and since the accident it has been 4.4. I changed the Air Filters, and noticed a slight change, but not like it used to be, and the pyrometer shows alot hotter than it prior to accident.

It use to run 10 on a steep climb, but now a smaller climb it goes up to 10 alot quicker.

My water temp is the same, but the drop in mpg is eating my profits up quick. I still get fuel at the same 2 places as before; have checked my fuel filters and no water or trash in them.

I did get new rubber all the way around, but it shouldn't drop it that much, same tread design as before.

Any suggestions or advice would be greatly appreciated.

was the turbo/aftercooler etc affected? Check the pipoing & hoses, clamps etc. & the charge air cooler itself.......

New rubber.. ding ding ding... takes about 50,000 miles for those tires to break in.

But I don't think that's the whole picture, there's something else. Check for leaks.
