Diesel World article
went from 17 MPG to around 23mpg driving at 67 mph. This all sounds good, I plan to eventually go with the improved intake elbow, change to the sythetics, not sure on the air intake kit or programer. The tonneau is out also.
anyhow I have been reading ads about the different front hubs that are available, does anyone know if they actually work and make a difference as far as MPG?
They used a PSD for the article, mine is an 04 FX4, I am getting 17.5-18 on highway now at around 69-70MPH.
The article was the first I have seen on other than hotrod trucks, Oh BTW went from around 250 rwhp to 411 after all was said and done. Good article.
