I would definetly upgrade the wastegate if you plan on the drag kit. You should be fairly safe at low boost, but the problem is that the tial wastegate suffers from boost creep which will destroy your engine real quick. If you need more help or have some more questions feel free to drop me an e-mail at

www.haiparts.com and a club
www.highaltitudeimports.com . We've been selling the drag kits for quite a while now...
