Thanks for all of the replies. I do have my Vacuum ref plumbed to my manifold. The problem turned out to be OIL. Everywhere inside of my intake tubing... Not sure what happened . I pulled everything apart and cleaned it. The MAF was coated in oil. I also pulled the turbo off and it seems fine. Could boosting with the snorkle kit have caused to much intake restriction??? Anyways I took off the snorkle kit and ordered a 12 inch K&N today. Hopefully everything will be back to normal>

Could your pump have failed intermitantly? This would cause you to have oil in your intake and tailpipe no? I know when my pump shut down I was blowing clouds of smoke and my muffler was drenched.

No sure. The alarm never went off and there is no oil on the exhaust side. I also found that my WG was full of water. Is this normal and is there a fix other than draining it on occasion?

The WG water issue was a common problem where ethanol or oxygenated fuels are used. STS just recently redesigned the WG tube so that it does not sit at the bottom, or moved from the 6 o'clock to 3 o'clock position. There is a thread from Feb 2006 that shows the new design. It was not too big a deal until those in the colder climates had their WG piston freeze closed
. Free boost increase but bad for tuning....

Another question about meth injection nozzle???
The 12" K&N is part #RE-0800. I went with the 14" Part # RE-0820. They were the same price.
One more question for you guys.. How do you know what is the best size nozzle for Meth injection. I have tried two different sizes. One that came with the kit and one step larger. They both seem to lower the temps the same but If I go to big will I start to loose power or do I just go as big as I can until it starts to miss????

I am not sure what is optimal but I am running a M15 ( 0.25GPM/15GPH with 100 psi pump) with 50/50 meth. Read the FAQ at AlkyControl to get some idea of what Julio recommends about tuning.
