Smoke....

Not burning oil at all, but I have not drivin it enough to measure the amount that SHOULD be gone to lubricate the seals. I had a blown engine before this one and the amount of smoke was much more than this, it smelt like oil unlike this, and it had oil building up at the end of the tailpipe while this one has a yellow liquid crap. I will take a pic of the yellow crap to show you what I mean.

That seams to be the main culprit, but could that really cause smoke like this? I mean the car doesn't know it is FI because of the stock map so it shouldn't really be doing anything different. The only thing that has changed is the intake system obviously and that the exhaust is running through a turbo now. How can that cause smoke?

so the easy way to do that is. open the document and hit print screen button on the keyboard. then open microsoft paint and push ctrl+v. After that your screen shot should show up and you can crop it to a proper size and save it as .jpg. wallah photo of it completed.

I checked my data (but remember i am NA) and at that speed and approx rpms, My long term and short term were the same at -0.16 off the base map. I dont think FI should really be that different though so I am assuming your trims are goofed up.
You should in the mean time post that data in the thread "Cobb datalogs" to see if those guys could be more help and also attach the thread you started here for them to get your history.

OK
you have -9% fuel trims and are still running 21% too rich for the load condition on that log . So about a 30% too much fuel would be called for if you reset your trims to zero .
Some possible causes :
Maf housing is too small . What are you useing - stock greddy turbo maf housing ?
Some other disturbance to your maf
large vacuum leak
Not sure if that level of fuel would cause the smoke but it's a good place to start ...
