really bad gas mileage

Throwing a free flowing intake and a free flowing exhaust on vehicles does indeed help, but manufacturers cannot do this legally across all 50 states. In the long run, it is much cheaper for them to produce one vehicle that is 50 state legal than it is to make special edition vehicles for states that need more equipment on their vehicle. IE California in this case. If you make a change to your exhaust and live in California, the modification must be CARB legal or you will fail an emissions test.
I am unsure about other brands, but I know in the mid 90's through 2000's, Chrysler played with the idea of producing trucks for sale in certain states. IE the ram. If you bought a California edition ram, the truck had two extra catalytic converters instead of 1 or 2 (Depended on the year) It was also during this time that Chrysler played with tuning that a person could buy aftermarket. They may in fact still do this for some vehicles, but I have not looked into it. In the past, they sold a different PCM called the MOPAR performance PCM that threw down a complete different tune compared to what the factory was putting out.
As for the argument about tire size... Chrysler is not out to cater to people who modify their vehicles. It is a hairy situation. Therefore, they will only adjust parameters that can be found in and on other factory settings. These tire sizes are a prime example. Why should they care or provide support for a person who wants to run a tire size differing from what they offered from the factory? Hell, they can barely take care of people who do not modify their vehicles let alone people who do.

Money for gas is not a problem was just wondering y friends with same set up r getting 3to 4 miles per gallon more . Just on here to try and get some info since the dealers don't know s&&&!! I'm trading the truck next week on a 2010 ram crew Laramie diesel making the appointment tommorrow for the lift and 37' tires!!
WOW! Money for gas must not be a problem if you can absorb the hit of trading in a 2010 vehicle already. You are gonna lose your A$$ on that deal!
Stay tuned for the upcoming "why am I getting 5 less miles per gallon and have way less power than the guys with the 2007 and before 5.9 CTDs" thread. LMAO...

and as far as my quote there OP, there really was no sarcasm intended. The FIRST biggest thing posted in the gasser sections is "how can I get my mpgs up" and the FIRST BIGGEST thing posted in the CTD section is how the fuel economy and power in the 6.7 CTD is nowhere near what the venerable, old 5.9 was (and all the emission CELs)...

There's probably nothing wrong with your current truck (until next week), the laws of physics are equal to all, but driving habits/conditions and the environment which you travel can alter your mileage.
Are you seriously dumping the gas for a diesel because of the mpg's? Good for the economy, hard on the wallet, but to each is his own.
