[TOMBSTONE LMM]

i just installed a turbo back exasut on my 09 lmm, its working fine and feels stronger but white smoke is coming out of the exaust like crazy....before i had just the dpf deleted and black smoke would come out just by stepping on it. but now with the turbo back alot of white smoke is coming out just by driving regurlaly..... what can be the problem?? id really appreciate it

what is the outside temp? Mine usually does the samething burning the moisture in the exhaust

 

[TOMBSTONE LMM]

the outside temperature is 82 rite now

Is it doing it all the time? Do you have any check engine lights or anything?

no service engine light, and its doing it all the time as soon as im driving it white smoke is coming out

HMM most definetly not normal. I dont know what to tell you to check being that it is an LMM. Your injectors should be fine. Just to make sure check your balance rates using EFI or a tech II. Have you checked your coolant level lately? Just to make sure it isn't leaking coolant.

what does the exhaust smell like? does it have a sweet smell or a fuel smell to it? it almost sounds like its trying to regen on you

This very well could be true!! I didn't think of that. If it is trying to regen you need to use you programmer again to be sure that you have regen turned off! If not and it smells sweet my thoughts are turned to headgasket but why would a truck running a 90hp tune lift a head?

i think it was the 09s quadzilla was having a problem with turning off the regen process if i remember correctly

 

[Chevyguy08]

you did download the dpf delete software off quadzillas website correct?

yes i did.

 

[Chevyguy08]

and it took it no problem? I would call quadzilla and talk to their tech line, im pretty sure it was the 09s they were having issues with

 

[TOMBSTONE LMM]

yea i know iv been calling but no anser i left them a message but they havent gotten back to me... this quad2 is starting to get on my nerves

 

[Chevyguy08]

Does the exhaust smell like fuel?

 

[TMX864]

ok im not familiar with the new motors but i saw a post like this with a lly where his EGR was stuck open. Something to think about

 

[Chevyguy08]

It should throw a code if the egr is stuck open, usually anyway

 

[subparwelder]

Yea every time I ever tried to call quad no one was home. Leave a message and if they feel like it they might get back with you. Good luck.
