I cant wait anymore for the warrnty to expire! I want more beef in my engine!- I'm planning to purchase a TAP Stage II kit (chip,filter,exhaust)<br> <br> With the stage II kit do I need a Turbo timer? Is that HKS blow off valve a good idea ? Any comments or suggetsions with the kit ? Is the Scorpion catback worth it? Pls help!-richie
