Just got my car back Sunday and all I am gonna say is wow.... I had the changes made to the kit that was suggested seems to be running great. I am a lil surpprised it has not been tuned yet but it is driving so smooth but I am not gonna really get on it till its tuned.
Heres my Set up: GReddy Oil Pan, Spec II boost Con, GReddy T Timer, Defi Boost, AEM Wideband A/F, GReddy Pullies, GReddy Catch Can, RP High Flow CAT, SP2 CAT Back....

2 things you ned to do to keep it reliable. The first of which is to tune it which you already know. Do Maddogs modification to the eManage. The second thing to do is to change the location of th oil return. Greddy likes it below oil level in the pan but this WILL hurt your turbo oil seals. It may be 2 weeks or 2 months but it absolutely will happen at some point. You need to either get the return moved to a location above oil level or get a pump on the return line. If you do these 2 things, it'll last for a long time.

Don't just do the wiring change - do my other fixes as well. They work together.
You may also find that you have a rich spot at mid throttle. Fix #4 is already employed in the newest E-Manage map on my site.

I'm not sure what you are advocating here, Fred.
Fluids find their own level, so the angle-of-the-dangle won't make any difference.
If you are worried about the turbo draining, you need to physically raise the turbo itself which would require some serious fabrication.
The way Greddy (and my system, too) have the oil drain configured, is drains downward and the oil outlet on the turbo is above the fill level.
However, it is true that many tuners would recommend a sump pump for a turbo mounted that low. Some how, Porsche manges just fine without one...
The real problem with the kit is the supply line - too much oil pressure goes to the turbo and that is what swamps the return line. In fact, it blows the bearings off of their seat under load.
Fluids do find their own level. Unfortunately we have a supply of oil being fed to the turbo faster than it can drain to the pan with the oil return below oil level. It takes longer for the oil to "find it's own level" this way than it does with it just pouring into the pan from above. Since the oil backs up in the turbo, it puts pressure on the oil seals and they WILL blow out in due time. Yours will too. It just hasn't yet. Porsche uses a return pump on their turbo cars.
Hey congrats Asheboro, I guess we're within 45 mins of eachother or so, I'm in W-S. I have almost the same set up as u, but no highflow cat or midpipe yet . Anyway, I was about to ask the same thing about fix 4. I am severed now, and I left the map the way I had it alrdy b/c it was tuned all on the subinjector map. But, ur map now is w/o the rich spike mid throttle?? Mine is ok, it's at 10.5 or so at say 4k, but I noticed it's usually in the 11's under full boost at greater rpms. I am close to getting the interceptor though. These E-manage fixes are great, I just don't wanna drive w/ it all the time and be absolutely 100% confident.
Greddy Turbo, Profec B Boost Controller, Innovate Wideband, Defi Boost Gauge, Custom grooved 3mm apex seals, ACT Heavy Duty Clutch and Prolite Flywheel, Denso Iridium Spark Plugs, Greddy Oil Pan, Oil Catch Can, Greddy Type R BOV, B&B Exhaust, RP Short Shifter and Tein S Tech Springs, and a crappy attempt at painting rims black.
Airflow tweak from 9% to 17% throttle in the 3k to 4.8k RPM range.
There is a "run-off" of the AFM there because of the size of the turbo. It is unavoidable, but its effect on the fueling is dependant on the sensitivity of the feedback circuit and the AFM. It will affect different cars differently, but the 25% pull on the AFM in those ranges will work pretty uniformly well in 90% of the cars.
It will actually cause a slightly lean condition at cruise.
On my car the oil drain was designed from the factory to sit below the level of oil. The only time I have heard of a turbo failing from the drain tube was because it was clogged. Now the oil feed is a much diffrent problem To high of a pressure feed will kill the seals.
