Tuning And Gas Mileage!!???
I have a question about a street tune on a '04, 2wd, 5.3 Silverado.... If I were to get that tune, how bad would it hurt my gas mileage, how much of an increase would i see in performance, and what is the typical cost of a tune? I was priced for $250 by a performance shop in FL "And which they said I'd see a noticeable difference in the truck from low-mid range, but the wheels would be what hurt me the most"... the are gonna tune it, delete the govenor, and adjust the speedo with my 22's.... So I was just wondering....And as you're prolly wondering, I'm already not getting good mileage with these 22's either.... I haven'tyet tried the K&N filter pak, the underdrive pulleys, or the long tube header kit set up....If i go that far, I might as well get the programmer, and save up for about a year and put a Magnacharger on it...LOL j/k.... But thanks for any help you can give me....
