Well I have the whole week off because of spring brake. I need to find somethings to do to the GP before I take it to the track in 2 weeks. I want some cheap things to do that will help the performance of the car. I was thinking of TB port and polish and I was thinking of making a new CAI with PVC. Will glass packs give me any gain? I was thinking about those too but mostly for the sound. Any other ideas
