I'm considering this mod in the near future and I've seen plenty of postings in the archives regarding the Garret Chip but I still have a few questions on it. 1. Is there another benefit to it besides more power ? 2. What is the increase in HP? 3. Are there any damaging effects on the car at all?(engine, clutch) 4. Should I wait until after the warranty period is over to add it? Pete 98 Blk/Blk X
