I would need to go look again at the tire and use the guide in the manual.
I really should just measure them tho.

 

so if i switch from 93 to 94octane and bump up wot fuel from 1.85 to 1.90 do you think We would be evenly matched or what?(me-my buddies hemi quadcab)....go back 2 pages to get the full story......

 

I'll keep on supporting this thread.Ive noticed as I drive more the truck seems to respond better. I tweeked my settings abit to see if it improves anything, It will take atlease 1 weeks worth of driving so that the pcm can get fully adjusted I believe.

I set the wot fuel at 1.90

shifts+firmness@ wot
1-2=5350+3
2-3=5350+2
3-4=5000+0

bumped octane from 93 to 94.

If yall think this will help out let me know. If yall think this will be worse off, let me know also. Thanks

hopefully this would put me even with my buddies hemi if not just an inch ahead!

Fastest I had with previouse settings were 0-60 in 7.21sec 1/4 in 15.54sec.
and fyi i have an 05 kr screw with 5.4 k&n drop in, snorkle removed, sido flowmaster, 3.55rear and optimisum!

 

Does the Edge feel like it adds 35 hp?

 

Yes, it does, but 35HP really isn't that much on a truck this size, but definitely noticable.

 

With the gears, and tire size set correctly I managed a 6.92 0-60 tonight. That's at 10 feet above sea level. Ambient temperature around 45 degrees. 93 in the tank with 94 programmed. No other mods. I'm initially impressed.

 

nice! I managed a measli 7.45! I will wait for a weeks worth of driving so the pcm can learn its new found power!

 

Ahh im still messing with it to break into the 8's... May best run so far is 8.9 for 0-60. i just installed E-fans so hopefully that will help.. Damn these 35's and 6400lb truck

 

Anybody figure out best settings for fuel mileage? I know tow tunning is suppose to give best mileage. Is there other settings that inprove mileage?

 

I just used the stock settings for the Performance tune and 94 octane. I picked up almost 2 mpg on the highway. It more than offsets the cost of Premium fuel and get to keep the performance too!! What a deal!!

 

The operating instructions have footnotes throughout describing which items to adjust for better mileage.

 

Kool Aid, how much does a truck like your(just like mine) actually weigh?
5500lbs?
6000lbs?

 

I have not weighed mine on a scale so I don't know for sure, but the spec sheet says 5300-5500lbs.

 

Which spec sheet gives these weights? I have been looking for a published weight for my truck but have not found one yet. I have found max weight but not empty weight. I assume that my truck will be at the very top of any range. Also is the 5300-5500 range only for 2wd Screws? I would find it hard to believe that a 2wd Reg cab XL is within 200# of a 4wd Screw KR.

Well if it helps at all i took my truck on a scale..

My truck is a Supercrew 4x4 with a fabtech lift and 35" tires (My tires are REALLY heavy). This was with just under a half tank of gas, my stereo system, and myself in the truck. I weighted in at 6300lbs.
