Time for new spark plugs and debating if buying a tuner for my 06 2500 hemi 6 speed manual is worth it..

Running a home made cold air in take and 2 cherry bomb glass packs, for 600.00 can I can buy a lot of gas...

Only timesI drive my truck is to home Depot or to take my dog out or on high way drives..

I don't tow anymore and my truck is just a hobby toy for now..

 

Wouldn't be worth it IMO, will give you slightly better power and fuel mileage but it won't be enough mileage that you would see $600 worth in your lifetime.

 

^^^^^^^^^^^^^^^
What he said.

 

Is the title supposed to be "Are tuners really worth it"?

 

Yup,
What they said^^^^^^

 

Fixed. Tuners are a great performance upgrade but don't expect any sort of mileage improvements. They are a mod only for the grin factor.
