Another thing - the daytime running light don't even work as far as I have seen.
I've only owned the truck for a week tomorrow....so just figuring out the tweaks on it.
Could very well be related to the after market NAV
Can't wait to install my MAC CAI and Granitelli MAF w/ CAI tuning...came off my 07
It really helped my 07....even with just a little extra HP, but i had some exhaust, which will be next on my 2003
