I have a 2007 M8 and I put an aero turbo on it a year and a half ago. I probaly have 700 miles on the turbo and it always ran great. I went out last weekend and up the trail it ran awesome and when i got to the top it was really starting to bog like it was running super rich or something. I finally figured out that the alumminum airbox came off and it was leaking air/fuel/oil out. I took it all apart cleaned everything and put it all back together, to find out it is running the same. I pulled the plugs after a test ride and they are really dry with a greyish substance on them ( not black like normal). The tips of the plugs are also a little white. I have always ran on the same settings on the pure logic box but i tried playing with it to see if it made a difference which it didnt. It is also only hitting 5-6 psi on the boost when i normally run 11psi. When i hold the throttle wide open it sounds like and old sled with jets that are like 5 sizes to rich. I dont know what else to look for or what else the problem could be, if anyone has come across something like this or knows what the problem is feeback would be greatly appreciated. Thanks!
