I installed the K&N filter and cut out the front of the air box. What a difference. The car launches much better now. It's a really great mod for $30. I added Redline Water Wetter to the coolant, and the car runs about 10-15 degrees cooler. I added shims to the wastegate and now I am running about 7.5-8 psi. The increased boost is nice, but it's not too much. I also replaced the diff oil with Redline synthetic. It is quieter - the old stuff was a little torched. All in all, the car is at 250 hp now. I am waiting to buy exhaust (about 3 weeks yet), and at that time I'm adding a boost controller. Also, I plan to put a cold air duct directly into the front bumper for better cold air supply.

When you say you cut out the airbox, what mod did you do to the airbox that improved the performance of your car?<br>regards cvl
