Seems like the tow was about 14-14.5 (about 70%city/30%highway.) Seems like Custom 87 Performance was a shade better. Truck is on '04 SCrew 5.4.
Tuner is the Gryphon (original, not CTS) I'll be doing a little more highway driving this weekend. Curious to check it there. I once (only once) got 18 an an all highway trip. It was before the Gryphon, but I had fresh oil/filter. I'd love to see that again. |
