I just installed my Edge/Attitude tonight. Yeah its a quarter 'til 2!!! Anyway, I was wondering what you guys were running all the settings at. This thing feels kinda weak to me. Maybe it needs to be broken in or learn something or something. Anyway, I would appreciate some feedback. Should I have stuck with the LB7?

Bump the low boost setting to 3 or 5, and wait till the engine warms up before you get on it to hard. Unless I power brake it is slow till it shifts to 2nd.

Sounds just like mine. Gm has bottom end turned down for smog control I believe but don't know for sure. I'm working on a cool fix for this motor and actually testing right now. Saw 125 RWHP increase with it. Just testing for now. Will keep updating as I go. Edited by: lly101

keep us posted on a fix for the bottom end. ive been running mine on level 5, low boost @ 4 and no de-fuel. making good power, not great, i did expect more from it. it takes off like a friggen train on the highway though, pulls hard from 65-100+

I have been running in Level III. Havent tried anything bigger. LLY101 please let us know about the tweeks!

How do you go 100+ my truck cuts out at 95?

Hoser - TTS Tow Tune, removes the speed limiter - very nice option http://www.dieselplace.com/forum/smileys/Clap.gif http://www.dieselplace.com/forum/smileys/Rock On.gif

I run mine on 0-stock and just adjust it up as needed depending on who or what is next to you.http://www.dieselplace.com/forum/smileys/Big Smile.gif

dwrat - hows that magnaflow down pipe set up ?? does it remove the cat ? and if so, have you heard any turbo bark from the edge ?

They call it "Down pipe back" but it is really cat back. Turbo bark 1 time, I think. It sounds just a tad louder, not really noticeable.

I'm not sure if you guys know, but the juice does not even turn on until the temp reaches 180 on the attitude display. That got me the first few times I drove the truck and wondered why it had no difference in power.


Anyways, I drive around in level 1 with low boost set to 5. When I get someone next to me who I want to race I just up the power level as needed.

338 - are you getting any turbo bark on WOT runs ?

I've had 2 turbo barks since my installation last week. One was on the first day of installation in level 5, the second was on day 2 in level 4. Both were with low level boost set to 5(highest setting). Since those 2 I haven't had any more. I've noticed the allison shifting pattern is alot smother now, so i'm thinking the turbo barking may have had something to do with the trans shifts. It only barked those 2 times when it was defueling between shifts. Edited by: 338_

hmmm - i get that friggen turbo bark almost always on WOT runs - trying to find a fix now for it - thinking about turbo back exhast to see if that relieves some pressure, thanks for the feedback

tbone1227, how much boost are you seeing? The max I ever get is 29psi. Are you getting the bark stacked or unstacked? I noticed your signature. Could to high a boost pressure and know way for it to escape(restrictive exhaust) be causing the bark? I also see that you have suncoast stage III, so you probally don't defuel between shifts? That probally keeps your turbo spooled way up. I'm just thinking out loud here, I am by no means an expert in this field. I can't believe nobody here has an answer to what is causing the bark or what could be causing the bark.? Did you try contacting edge?

im waiting to hear back from edge now as i was hoping it was just a programming matter perhaps... i do think youre onto something in regards to the why's as the 2 things that I thought of were turbo boost and restriction on exhaust, was thinking maybe a true turbo back exhaust to start to see if that relieves some pressure and in regards to the turbo boost and no-defueling ( which is correct - i run it on no defuel ) but it will bark on highway on 5th gear when locked, granted it could be shifting from locked to unlock on WOT on highway ?? it will also do it in 4th gear locked on WOT as well although this might be the same as 5th gear mentioned above. i wonder if that being the case with shifting from locked to unlock if turning defuel on may help ?? any thoughts on that set up

Hmmm??? Let all of us know what edge tells you.

My "release" version does not bark at all. It doesn't even bark stacked with the power pup. However, I also put the cat back on at the same time I got the release version so I dont know which one really stopped the barking. WOT I see 30 lbs. boost max also, even stacked.

nate - you have the full cat back system on ?? thats the one that bolts on right after the cat, right ??

I'm not sure if you guys know, but the juice does not even turn on until the temp reaches 180 on the attitude display. That got me the first few times I drove the truck and wondered why it had no difference in power.

My LB7 Juice comes alive at 142 degrees. Why would the LLY be different?

I don't know, I didn't engineer the boxhttp://www.dieselplace.com/forum/smileys/Confused.gif. All I do know is that mine doesn't kick in till 180. Is every other lly juice the same? Someone else chime in with an LLY.

You are dead on 338. Shes a zombie till about 180 on the monitor. I don't know if its programmed that way, or if thats just the way the LLY is?

Yep mine too . It is a safety thing that Edge engineers into the box to keep from wearing the engine until she is warmed up. I think it is a good idea so the ol Duramax will hopefully last longer.

I have the production release of the Edge and it starts to kick in about 135-140. During the warmup period, it will cough a little white smoke during light throttle acceleration around 1800 RPM. If you accelerate harder, it won't happen, however I am real gentle on it until the temps reach 180. When them motor is up to full operating temp, it runs clean all through the RPM band

Well this 180 degree temp sure explains why my truck feels so slow in the morning before fully warmed up! I'm running low boost 5, defuel all unlocked shifts (until suncoast III goes in), haven't had it bark yet. I run around ALL day long in level 3 w/ trans on tow haul, for some reason the monitor shows no slip in tow haul, but slip constantly if it's not on? (I read back on some posts and no one could seem to figure out what slip attitude monitors). Better safe than sorry, I like that to read zero.
Anyone running level 3 w/o shifts 1-4 defueled? I'd like to try that. It really lets up between shifts, but don't want to mess anything up.

The reason it doesnt slip in tow/haul is the TC will lock up in 2nd. Without it on, lockup in 5th.

I tried it the first day I installed my juice/attitude. Trust me when I say it will put the trans into limp mode. At least mine did. Maybe if you give the trans a few hundred miles it could adapt and not limp, but i'm not trying it anymore. I had to pull off the road, put the truck in park, and shut it off to get it to operate normal again. It sucked!

When it limped it w/o defueled shifts what level were you in?

Actually if you pull up the display for the gear on the ATITUDE with my SunCoast-L3 it will show on the display and you can feel TC Lock-up in Normal Mode in 4th and the 4-5 shift you feel it lock down again in 5th........


it does this on a 2002 with LB7....not sure about the LLY

Mine doesn't show lock till well into 5th in normal mode.

running the suncoast stage 3 on lly and on o/d locked out but no tow-haul it will go into 4th, then lock 4th which you can feel it do, and if i get into o/d it will go into 5th, then 5th locked

When it limped it w/o defueled shifts what level were you in?
