we never got the chance to install the catch can. I think the smoke that he is seeing may be from the return line, cause yes your right if there was a bad seal on the turbo it would be smoking from the tail of the car.
The return flange/gasket/an fitting all need to be checked for a good seal, cause we did have a problem with it when we were tuning the car and the return was a bit loose, not sure how but it was leaking from around the threads, was tightened but but I think it may have come loose again..IF by chance its loose again I think the best idea would be to loose the -an fitting and go with a thread-by-barb fitting like what we used on the oil pan and just clamp the hose to it..but he needs to check and see if thats the issue.
Carlos, check that oil return fitting coming off the fitting and let me know if its loose again. If it is I can get you the barb fitting and ship it to you with a clamp so you can swap it out.

Just got word from the shop that they fixed a leak on the turbo and now its smoking even more
(the leak was from the connection to the manifold)...maybe its just burning off whatever was there..idk. Skeptical to retune because it was running good with turbodremz's tune. Wastegate is covered in oil.

whoops i thought you meant the engine bay. you should be able to drive it around at least if its just the turbo burning off some oil. are you sure its not smoking from gas?
your old settings added in 26% extra fuel at 2200 rpms from 0% to 94% throttle.
Thats alot of extra fuel for parts of the throttle that dont ever even see boost 0-40%.
This is out of the stock ecus ability to learn. Im honestly surprised it can even run with the mixture that rich out of boost.

Okay guys. Really weird stuff going on now.
I drove the car out the shop and heres whats happening..my boost gauge is jumping to like ~5 vacuum with the smallest amount of gas, she moves, makes alot of noise, still smoking at the tail(not tons but some*white*)..and as for the oil leaks, they seem fixed..i checked and double checked and honestly the lines are all good...it is running rich as a dog and idles at like ~500 rpm on the verge of dying...on the drive home from getting gas, I had to brake with my left foot and keep the idle up. All the vacuum lines on the throttle body and intake mani are good and not going anywhere. Maybe the retune and catch can are the last things she needs? But why the low idle? and why the smoke?

yeah, if you tuned the high already it should be the same.
when you mess with the low settings it makes the stock ecu go crazy.
as long as you have the stock injectors it should be set to zero.
If you do a search on safc and resetting your ecu you will find that most who use an safc figure out that once the ecu starts learning too much you need to reset it. If you have a good tune the ecu wont suspect anything for a long time and it always drives the same. if you have a bad tune then the ecu will figure out something is wrong much quicker and you will have driveability problems that seem to go away when you reset.

Good news
So heres what I did.
SAFCII(junk with OBDII)- set low rpms to 0% across the board.
TPS-40lo and 80hi
Reset the ECU.
1st Trial run- Great AFR's at idle, and cruising. Absolute optimum.*for now* Lets pray.
Cons in first trial run- White smoke after cruising and warmed up and parked at idle. Random popping from exhaust. AND, extremely low idle*which i think is causing the pop. Its idling around 550 steady. She's gonna cool down for about 2 hours, then the second trial run comes.
The afrs should stay good...the idle is something I need to fix. And we need to find the culprit of the smokey exhaust. The valve cover gasket was changed. Im hoping its just condensation or stuff burning off the turbine wheel in the exhaust housing or in the exhaust piping.
Opinions!! Thanks turbodremz and Ali SC3 and everyone for getting me this far. Lets see if we cant finish this.
I need a good walkthrough on how exactly to bring up my idle.
Ashtray-
edit: 2nd trial run
AFRS were great yet again...it seems as if though the idle fixed itself, and im only getting that popping sound when i downshift. As far as smoke its strange...I came to a red light and she was like a dragon..I couldnt help myself seeing such great afrs I decided to boost just a tiny bit, after that, the smoke really dissipated but then the afrs started to wanna go a bit lean on me. The exhaust smells like gasoline*not like crazy* but it does smell like gas.
IDEAS! Turbodremz, Ali sc3 where ya'll at??!?
