So I ended up putting a fresh 20g after the small 16g took a crap on me.Checked for leaks and started right up.Went to take it for a spin and it builds no boost at all.Just bucks and stutters.Havent had a chance to do a BLT but it was running fine this morning pre turbo swap,well besides smoke bellowing out the tailpipe.I did change out the injectors ,fuel pump and the fuel pressure regulator last week but it was driving fine enough.Only thing I can think of is that I might have overoiled the K&N filter on the intake after it was cleaned and it got on the MAF.Any suggestions other than the BLT?How can I read the logs to see if the MAF is doing its job,Im new to this.

You check for shaft play? Prime the oil system before start up? Where did the turbo come from? Gotta do a boost leak test! That should be a law. Anytime you mess with the turbo or intake track you need to do a blt!! ;) Before you do anything else do a boost leak test. You can't just assume you don't have any leaks. With your issue I don't see why you wouldn't start there. Lol
 
Yea,ran out of daylight and had dinner plans so I didn't get a chance,just checking out any one elses opinion so I have more insight when I do get to it as I work long hours during the week and only get a few hours really on the weekends to tinker with it.
 
Ok so a tree fell on the Mrs's cousins car last night so she had to drive my daily and I took the eclipse to work.Almost got tboned stalling out merging on the road,that was an exciting start to the day.
On the process to do the BLT I noticed the clamp from the intake coupler to the turbo was loose so that was one issue.There was another leak at the injector and an intercooler pipe but nothing major.Holds 20psi ok enough.Took care of those and drove home and noticed it was doing the same stutter ,no boost run like crap deal under load.
So I hook it up to the laptop and noticed the injector settings either didn't hold for the new ones or somehow it changed itself back to the evo injector settings.So I switch it back to the new injector settings and the car cut off and it won't start.Just sputters but it doesn't catch.
Unplugged the Maf and it runs like crap.I'm thinking it's either that or the harness that runs to it.It did get sprayed with oil from the old turbo.So my question now is looking at the log above can I diagnose a malfunction on the Maf?Car won't start at all and the plugs are newish and they look normal.
 
Seems like it,after it was swapped out,car runs and boost smoothly.The old one had a nice oil coating on the little wire,possibly could have gotten away with spraying it with some cleaner.

For future reference, the karman vortex style MAF sensor (what you have) should not be cleaned. MAF/MASS cleaner can cause more harm than good.
