How many mpg's can a tune add to a stock 4.8l? im trying to convince my dad he needs a tune on his truck and was just seeing what u guys thought. i dont care about the brand of tune at this time, just estimates on mpg. when the time comes ill talk to him about brands. leaning towards nelson on this one tho.
mine added 3-5mpg thats with the 22''s
well im hoping to convince him, and since ill prob own the truck in 3 years or less it only benefits me to go ahead and have it tuned so when i start modifying it for performance thats one less thing ill have to worry about then :)
my '07 gained 2mpg with the trt tune.
Dustin, you can have a tune based upon gas mileage vs. all out power. I imagine you could see 3-4 MPG better with a mpg tune...
he saw 21.5 MPG last tank, thats great for the 4.8. my 6.0 gets about 18 MPG when i drive right. usually the 4.8 gets worse MPG than the 5.3's though i guess better than the 6.0.
yep..my 4.8 gets 18 at the most...
i wouldnt be surprised if his math was wrong lol. itll be a great truck for my next build up.
