You were getting 17mph on the highway?! I only get 12.5 on the highway and 9.5/10 around town! Granted I have a heavy takeoff at the light changes but that shouldn't be that great of a difference on the highway between my '03 and your '04 they are both the 2 valve 5.4 engines. What other mods have you done to get the improved mpg? Improved hp doesn't necessarily give you better mpg's?to me...its worth it...although you may spend the $400 upfront...throughout the year you will save more is youre wanting gas mileage...i have superchips and love it...my mpg's increased from 17 to about 23-24 mpg's depending on how i drive...and other modifications...you will feel a difference in shift and take off pending your settings...i know i saved money withing the 1st 2 months of having mine

Hi All I'm new to this forum and am really enjoying the info! However I'm a little confused concerning Hypertech chips...I called and confirmed that they do not support shifting options for 08 Expys yet one or two people have claimed the effect on the shifting was worth the cost...can someone clear this up for me...and Thanks
Some of the programmers allow changing the shift points and trans line pressure by 25, 50,75,100%. Unfortunately, that was not an option for the 08. What can be done is raise/lower "redline" before shifts +/- 100-500. The rest of the drivability feel comes from the program. I ran mine on the 87 tune and +400 on the rpms. Sadly, I sold my Expy, but still have the programmer if interested.

Your post is from a few months ago but wanted to see if you still had this tuner and if you did, if your looking to sell it.
I have an 07 XLT
Still have it, will gladly part with it, just collecting dust on the closet shelf.
