what have you guys changed on your edge to give you the most power and fastest times. so far ive just changed the shift firmness on lvl 2 but i see all you guys getting like 15.5 1/4s and im getting like 16.8. whats the secret?

 

Yeah i would also like to know what you guys have yours set on because my fastest 1/4 time is a 17.5 but thats also with a 5 gallon air compressor, a tool box that is probably pushing 150 lbs, and a passenger. Thats on level 2 running 87 octane also. When i get my CAI and run some 91 octane on level 3 maybe i can get in the 16's. I raced a V6 stang the other night and we were neck and neck for the first 60 mph or so then he left me. I spun tires off the line a little to.

 

This is what Im running right now, I used to run a LOT more aggressive tune on my last truck and all was fine.

• 1-2 WOT SHIFT: 5200 rpms
• 2-3 WOT SHIFT: 5200 rpms
• 3-4 WOT SHIFT: 4700 rpms
• SHIFT FIRMNESS 1-2: +5
• SHIFT FIRMNESS 2-3: +5
• SHIFT FIRMNESS 3-4: +0
• REV LIMITER: 5400 rpms
• WOT FUEL: 1.3%
• TIMING: + .25

I think thats it. .

 

17.5! Wow.....But it does have a lot to do with the weather also. My stock Roush tune uncorrected times were about 9.6-9.7 with the best being a 9.500 (14.9 1/4 mile) but that was on a fairly good afternoon with low humidity and around 75 degrees. I went back the other night and got a SLOW 10.0 and it was 95 with SUPER high humidity and major wheelspin off the line. That was with a full tank of gas (35 gallon tank) and all the other crap I have (tonnea, spare, 75lbs of traction bars)

 

Matt 05'FX4,
Not to get off subject but i thought you were Bama tuned not M.T.?

 

I'm at 5300 FT so just running the stock tunes right now. I am running level 2 at 85 octane with no problems and have run level 3 at 88 octane without any problems. If there are others at altitude that are running custom levels I'd love to hear from you.

 

IVe seen some guys running +15 on their shift firmness. I saw in the manuall that it might be bad for the tranny if you change some of the settings to sudden. I guess you have to break it in. I was playing with the shift firmness and it goes all the way up to 25. Has anyone done thise.

 

I decided to try out your tune on level three. Rather mellow but very streetable.

 

Here is what I am currently running:
lvl2 with 89 oct.
shift firmness +5 on all shifts (I used to run +15 on all shifts on lvl3)
shift point +2 on 1-2, rest are stock
timing +1.00

The reason that I don't run +15 on the shift firmness is because I started to pull trailers more, and I figured that a high shift firmness and a few thousand pounds was a bad comination. My best 0-60 so far is 8.1, I did think that was too bad at all. I havnt done any 1/4 mile runs.
