would you tune it?
my dads truck is getting around 15 mpg in stock form with his 08 with just an intake. he is very pleased with it as he is getting 15 mpg just driving around, not even on the interstate. i have been telling him to get exhaust and a tuner.
would it be wise to tune it when he is getting crazy milage for a stock 6.4? would he still see a fuel milage increase?
just curious because anyone else with a 6.4 around me is only getting 10-11 mpg
