Overall, I'm fairly happy with the MAF mod. I'm not quite as blown away as, say, Nay
is, but still this seems to make the truck run a little better. This morning going north on 470 between Morrison Road and I-70 I was able to hold that hill past Bandemiere, 70 mph without it shifting out of overdrive. Before to do this I would have had to have been in power mode, or turned O/D off. So I guess it's got a little more "stayin power..."
Looking forward to seeing some highway mileage next week.
