wow so yeah i replaced the thermostat and now my truck runs about 190 and feels a lot better. hopefully i will get good mpg now!!!!! my truck has been getting 13 mpg terrible i know but i thoguht it was becuase a bad injection pump. so i replaced that becaus it was bad anyway and also put an airdog 2 on there. but do you think running at 145 has been the whole raeason that i have been getting bad milage?

 

My thoughts is that it contributed to the bad mileage. I havnt run my MPG numbers yet since I dropped the new stat in but it just does seem to be peppier , more efficient and I don't blow quite as much smoke out the tail pipe.
