The fastest my truck has been is about 100mph, I dont see a need to go really fast in a big truck. The fastest Ive ever gone was about 150mph in my old car on the highway.

 

i had that same problem with my truck but, then i got the guys at national speed to put me a custom tune on a SCT X3 and i pulled out of the parking lot burning the tires off. also i only have to run reg 87 gas.

 

Mine hasnt turned it into a monster either just better shifts and unlocked the speed limiter.

 

did you get any custom tuning done when u got your SCT

 

Ya I got custom tunes. I got 87 economy adds just a little bit more power. Then I got 91 tow which helps alot when I have towed and saves some gas mileage. The last one I got was 91 performance. I got to take it easy on this one. The truck is real touchy on the throttle when this setting is on. I love this setting but with gas going up its hard to pay for 91 when your unemployed. Everyonce in awhile I will run 89 octane but just lower all the timing settings by a few degrees so it wont hurt anything. What kinda you got?

 

is it just me or do some trucks performe different with the edge then others mine seems to got like hell with it in and some ppl say it didnt really do anything to there trucks....to me it woke my engine up and lets it haul azz...question about the cai do i need to unplug my battery so my computer will know i have a cai??

 

good question...I've noticed the same thing


My old 2006 when stock was a decently powerful truck, and I could easily break 'em free and make some noise from a stop. Wouldn't win a drag race, but not bad at all for a 6,000 lb monster


But then I hear other guys saying their trucks can barely get out of their own way....


IMO, it has something to do with the PCM tuning (obviously)...and it seems the FFV trucks (mine was) seem to do better in the MPG & power department




also, the tranny "learns" your driving style. so it shifts accordingly. so if you drive it slow and reserved, then try to get funny, it won't respond correctly.

You have to "train" it to your style of driving...I apparently drove mine sorta hard. My wife says I am somewhat aggressive

 

that must be why mine seems to GLH when i got it new i dont think it had one easy day of driving ok well maybe a few but never had any problems with it so y change?? haha...my buddys tell me that they would never buy my truck cuz i guess to them i beat on it to me im driving it like a truck i get pretty decent gas mileage i mean its a truck not a honda or those goofy battery cars i can afford gas so i let my baby drink it up

 

I got a 87 octane tune and a 91 octane tune they got 37 rwhp with the 87 tune and 43 rwhp with the 91 octane.

 

Ok I gotta ask I have a superchips flashpaq on my 4.6, and it really woke it up I was amazed when I first installed it. Would it be worth my money to sell it and get one of these custom edge's everyone on here is talking about. I think the display would be pretty cool, but how much better could it really perform?

 

if i were you i would get a SCT X3 with a custom tune because its a tune set up for your truck like how you drive it, where you drive it ,and you can always change the setup if you get a new mod. EDGE is ok if all your doing is a CAI and exhaust but if your looking to do more you need to look into getting one that you can get a coustom tune on.

 

yea as i recall and the reason i went with the SCT is that you cannot custom tune an Edge.

 

but if you get the gryphon, a cracked edge then you can get custom tunes for it, and still have the display!

 

i didnt get the gryphon because i have heard bad things about the display. That they go out quite often. So i opted for the SCT and will be getting the PLX gauge shortly. Do a google search this thing is incredible and it is only about 100 bucks more than the livewire from SCT when you put the X3 and PLX together.

 

'06 4x4 5.4L lar scab, I've had an evolution for a couple months, and I'm in that group that can't really tell if there's a difference, I'm always in 3, or 2 when towing but I'm rarely over 3000rpms, I am interested it going into "custom options" 3 things: Standard Shifting-increasing, Torque Converter Lock Points-increase (the evo instructions read if you increase Std Shifting you have to increase Torq Con too), Timing Adjustment-increase too, Has anyone done this
