I already have a cai 180* t-stat sparkplugs electric fans I need a free or under $25 mod I have the weekend off and I am looking to improve mpg sitting at 16.5 now I know plugs and wires are over due and that will help but I only have $25 wires alone cost about $30 fresh rubber in needed too, but $225 a tire is 10x more than I have for this weekend.
I'd say the 50mm TB mod but that wont get you any real gas mileage... maybe take the 180 state out and go back to 195 since the pcm is designed to run on the rich side until in reaches full temp... others here who have done testing with both say the 195 is better for mpg and the 180 is better for power... they are often two opposite goals...(That being said I noticed no mpg difference between the two myself)

he could also remove the 47mm bottleneck above the stock 50mm hole at the butterflies..making it a true 50mm throttlebody...I did this for like 8 bucks with the cost of the dremel bits... some people pay a hell of a lot more for someone like fastman to do it for them... but it will allow more airflow which means more fuel will be consumed... it could go either way as far as mpg savings...
free and supposed power increase (very minimal if any) BUT you air intake will be louder

Huh? You mean to say that Dodge engineers didn't have a clue what they were doing by installing a 195º thermostat for well over 15 years?
You need to quit drinking the 180º thermostat Kool-Aid. Installing one will not cure all of the vehicle's engine woes, cure athlete's foot, or balance the federal deficit.
