I started off with 3.5 turns on my wastgate and the car seems happy. I do not know what my boost pressure is yet, I'll put a gauge on it soon. In regards to the 20+ lbs peaking, there is a small crimp in the hose where it is going through the fuse block into the passenger compartment. Maybe the crimp is doing something strange to the readings. Thing is though, the factory gauge does the exact same thing at the same time. Granted the factory gauge is not graduated, but it is doing the same little peak thing. Also, there has got to be something strange going on with the car since mine was able to stay right along side with it from 0-110+! (it almost looks like we aren't moving because the cars stay in the same position with eachother!) With all of the added boost that car should make mine look like an escort. When was the last time the fuel filter and K&N were cleaned? How about the plugs and cap/rotor replaced? Threre has to be a reason why the car is not screaming like mad. Kai, I can help you replace all of the stuff over a weekend but since Terence is here, can you lend a hand on the maintenance questions? The car is in sweet condition but it should be faster than what it is now. (either that or mine is doing something strange!) Also, Kai, do you have all of the goodies for the HID kit at the house? If you can, bring it with you during "lunch" today. I want to see what it looks like. Anyhow, Terence, I like the work you did on the 850. I have been helping Kai with it and the car is sweet. How did you keep it so clean? Well, gotta run.
