Maybe a little more smoke on hard acceleration... MAYBE.


Do you have a private email? I tried to send a file to you but it came back on the email you gave me a few days ago. My email should be listed in my profile.
 
Just how slow is it?


Any chance the transmission is slipping so it can't put any more power to the ground?


Bypass the wastegate solenoid and take it for a test drive (vacuum straight to the turbo)


If you can't feel a difference in the power then something must be wrong. (if you don't let off after about 10 seconds or so, you will set a code and loose power till it is restarted)

Whatnot.


I think the power is getting to the ground, brake stand will spin the wheels. (especially since i noticed both axle seals are leaking but thats another day).


0 - 60 in 15 seconds, didn't change with exhaust and didn't change with bump, no boost guage but you can sure here the turbo whine even before the exhaust upgrade. Times are run in 'D' everytime, but there might be a shift issue, hense me wanting to email TDG a file. ( 0 - 60 in real time, with cool exhaust sound...lol)

Should be able to reach me there, last I checked for some reason I could recieve emails but not respond.


I'm really dumbfounded that your not seeing results. I can guaruntee you 100%, that what you did increased your fuel delivery and I've seen for myself the difference it makes on other trucks. Any change in startability, engine/exhaust/turbo sound?


I'm sorry, did you say, 0-60 run, with sound?? send that puppy!!!Edited by: Texas Diesel Guy
 
Even if you have the boost working like it is supposed to you will only be getting about 6 PSI.


If you bypass it you should be able to feel the difference starting out. (you can just reverse the 2 lines at the solenoid to bypass it)
 
Or just run the vac line direct to the actuator.


I think I'm running close to this level of vacuum now with the resistor situaton resolved. I'm peaking at 15 psi when I peg it. That's all you'll should see with it run direct.
 
I think I might crank the turbomaster way down tomorrow and see what it will do. My gauge only goes to 15 but I don't have any resistors in the map right now so I can use the scanner.


All I know is that it felt weak when I backed it off to 14 psi

Just reverse the lines at the selonoid? Thats it, that easy... ummmm... how long could i drive that before throwing codes or going to limp?


TDG the file is sending, just not sure if i'll get it back here. Let you know in a sec...
 
I'm glad the JC whitney guage I have goes past 20 psi boost (more than enough) and 30 psi vacuum. At first I thought I'd never need the vac function, then measured the vac pump and solenoid with it. Edited by: quantum mechanic

Sorry guy's i didn't leave, was just trying to email TDG, something must be wrong with his email. I will try reversing the vac lines tomorrow.

Vac lines reversed and drove for 30 miles, 0-60 unchanged. Left my foot in it for the 15 secs +, no codes.


Prior vac tests showed 23 in hg coming to selonoid and 13 at turbo, checked the wastgate diaphram by pulling the hose and moving the gate with thumb over diaphram inlet and appears to be just fine with no leaks in diaphram.


Suggestions?
 
Put the hose from the vacuum directly to the actuator. Take your WG solenoid out of the equation.


Just think how different you'd approach this if you knew what boost you were making. When you switched the lines it should have jumped up to 15 psi or there's something wrong there.


Being able to read what's going on is invaluable. I didn't realize how little boost I had 'till I guaged it.

QM, I don't dissagree with you in the slightest, but with my busy work and hardly ever get time to get to a shop i try to do the best i can here in the field, boost guage is number 1 for me to get next, then pyro, i will be making a 3 hour journey this weekend pulling a 10,000 lb trailer and don't want to cook this thing just yet. When i installed the exhaust on a day off it was in a local shop, nearest place to me to buy guages and stuff is an hour away from there.


I may get a guage later today if i can get away for a couple hours here, where's the best place to install it on the intake?
 
You should have really noticed the difference.


When you put the lines back, was one of them holding vacuum still? If not, you might have a leaky line or actuator.


You could run a new line directly to the wastegate actuator from the pump and see what it does.


You did check the airfilter didn't you?
