Man, my truck is still slooooooooooooowwwww...... I did a 0-60 run on 93 octane tune and got a 9.24. I have to try this again, can't be the best it can do. I ran a 1/4 too, but was watching for traffic coming up behind me and missed the green light, started with a reaction time of 1.33 ran a 17.0 @ 85 mph. My mom's Chevette ran better than that. Needless to say, I will definitely have to run it again. However, I can say that it certainly is running a hell of a lot stronger than it did stock and is stronger than the 87 performance I had done too. I just hate to think how slow it would have run stock, since it feels like you're pulling stumps on stock tuning.
However, I can say the average gas mileage on the Gryphon is showing a +1 MPG increase over the Edge tuning; and that is with the runs I made and a fair amount of stop and go driving, jumping on the gas a fair bit.

I played with some of my settings and got a 7.1 0-60 and a 16.4 at 83.7 mph in 1/4 mile. stock supercrew with the gryphon and 87 perf tune. Temp was +8 celcius. My reaction time was an embarrasing 1.5 I jumped the gun on the first run and wanted to be better on the 2nd...that didn't work either.

Kinda sad isn't it? How can we miss the lights so badly! These trucks are just so darn heavy though. My buddies old '68 Chevy w/ a 307 would smoke this thing. We tried doing some timed runs years ago, and he couldn't get a decent launch without totally lighting them up and was still over a second quicker. Like I said, my mom's Chevette was quicker. Granted it runs completely different now, the tunes actually make this truck enjoyable to drive, almost as if it lost 1500 lbs. of weight. It just needs a set of gears to help it overcome the weight.

The best 0-60 time I could muster is 9.04! :sadface: Hoping some custom tuning helps this out a bit.

Question

I tried a couple 0-60 runs today:

Stock: 12.1s
#3 Canned 93P: 10.6/10.7s
#2 Canned 87T: 10.5/10.4s
87T (WOT=160/Timing+1): 10.5/9.71/9.75s but was hitting rev limitor
87T (WOT=160/Timing+2/Rev 5350): 9.72s but was still hitting rev limitor

I have a 04 4.6L W/CAI and was told that the only program that I could used until I get my custom tunes was #2 87T
I am running 93 fuel!

Does anyone have any suggestion on how to improve on these numbers?
Also does #2 87T have a max speed & Revs that I shouldn't exceed?

If acceleration and towing is more important than top speed and fuel mileage, then a set of gears would probably be the biggest help. If not, then I'd suggest more hard parts like headers, cams and such.

Personally, I'd like to be able to do all of that on my truck, but time and money dictate otherwise. Besides, the custom tunes have helped enough right now that I am pretty happy where I'm at until $ improves. All I'm hoping for right now is a set of gears since I haven't too many opportunities to get to open roads where I can really open it up.

I must have not been clear!
NOT by changing any parts but buy tweaking the 87 tow program to get the most out of it?
Without overloading the engine!
Has anyone adjusted their settings that resulted in a substantial improvement?

I have 06 mark lt 5.4 with custom 87 performance tune and the gotts, the best I could do was 9.05s and 16.99 ( looking for a little better)
Is there a big weight difference between f150 4x4 screw and a mark lt?

Thanks

Theres not a whole lot you can do with the gas engines as far as getting substantial hp gains. Another thing, the 0-60mph and the 1/4 times are inaccurate, meaning they have a quite large level of uncertainty. Just keep that in mind when you run these tests.
