how are you logging boost? i mean is what you are telling us what u see or from a log?
E85? how did u dial in your airflow at idle? did u do all the cruise and idle adjustments?
I get pretty rocking by 5k (20psi plus), its been a week or so for me.

I am just watching the boost on my gauge which reads pretty accurate, hits 16psi by 6k and holds, can't log it yet, but I should get a map sensor in the future for such purposes. The boost is pretty linear, 5psi by 4k, 10psi by 5k, 16psi by 6k, which is weird.

Standard 92 pump for gas, no e85 for me. I put in the basic settings for my injectors, messed with dead time a bit for the low trim and I got them within 2% of zero. I'll keep logging the next few days and see if they change much.

Once I fixed my timing my airflow per rev went from .37 down to .32 or so, much better according to the link manual.

Fix the boost leaks and exhaust leaks, and then bring it to shane for fine tuning.

Are you running the 2G MAS still, or do you have the MAFT?

He is running the 2g MAS still, Unhacked...

So far so good. Check the comp. cover that is where mine was leaking from, i think it loosened up some how.

Do a boost leak test and I would get the sensor so Link can track boost. Then have shane tune it.

the wg is set for for 22psi unless you changed the spring in it I ordered it straight from tial with that spring.

Scheides and I did some diagnostics over at his place Sunday afternoon. I originally went to change to my summer tires (forgot my jack in Iowa) and do a boost leak test, but we ended up doing a compression test as well.

The first obvious problem was the sludge in the intake pipe, coming from the compressor housing. It looks like an oil/coolant mix, which could explain why there is sometimes oil or coolant out the exhaust after I get on it. See pic below.

We then did a boost leak test and found two major leaks. Out the valve cover and out the dipstick. Not a little air coming out, a lot. It probably took 30 seconds to fall from 25psi to nothing. So then we did a compression test and got 150, 151, 145, 145, so that looks pretty good. At the time we didn't know what was going on, so we called it a day.

Then Scheides PMs me last night and says it could be the turbo causing all this. If the seals are really bad on the turbo then the air could get into the center section and into the oil pan, then out the dipstick and valve cover. Seems logical enough to me, since I know a lot of oil/coolant is getting into the compressor housing. As soon as my Red gets here I'll send in the turbo to PTE to have them look at it. 234 hp FTL.

What is your compression at with the engine build? Don't you have 9:1? If you do.. then your engine makes really low compression compared to what it should be, I think.

Sucks the turbo is junk..
