Best I'm getting for the 0-60 is 8.5 to 10 on all my runs. That is on every setting including 87 custom perf. I've got the 4.6 with gotts mod, but also alot of heavy metal like tools and a grille guard.

2006 lariat, 5.4l, dual flowmasters w 2.5 in pipe. 0-60 7.64 with 93 octane canned performance tune. pretty serious tire spin. could probably get under 7.5 if i nailed the start. havent done 1/4 yet. my 0-60 was 9.64 or 9.68 w/o gryphon.

I ran it again now that we are "enjoying" winter weather..... Yes, I'm being sarcastic..... and my 1/4 mile time dropped by a full second. I guess dropping about 70 degrees in intake air temps. makes a nice difference, even if you can't feel it. BTW, this time was with some wheel spin too, which was nonexistent on my previous 1/4 time. Now if there was a way to keep these temps in the single digit range during the summer......

I wonder if winterized gas is also playing apart in the dropped times?

In the cooler temperatures, you're getting TWO effects that contribute to power. BOTH the fuel and the air are colder, so they are somewhat more dense. This adds up to more energy per fuel/air charge in the cylinders, so, you should see better acceleration. You pay for it though in increased fuel consumption.
As an aside, this phenomena was VERY apparent in the planes I used to fly. In the winter, our jets would just "leap" off the ground (but you couldn't fly as far without refueling). In the hot Texas summers, the old T-33s that I got my basic training in would almost not make it off the ground before we ran out of runway. ![]() One of the preflight calculations you do is "takeoff distance". It needs to be less than the runway length or you don't go. And, a turbojet engine is really just a glorified diesel engine. (It will even burn diesel fuel - but it needs jet fuel for the anti-icing properties). - Jack

Jack's got a good point. But I have also noticed that my truck runs different when they make the switch. I also remember Bill recommending to someone who was having trouble to run 91 tune even though there was 87 in the tank. Maybe they mix the winter stuff to resemble the higher grade fuels.
