Okay..well after dumping a bit of bank into my xB i have the fallowing either installed or on order..

Injen Short Ram Intake
HKS Exhuast
Perrin Pulley
I'm waiting on headers because im deciding if I want to turbo the car or not.
Grounding Kit
Voltage Regulator

Now what I am wondering is what else can I do to the motor to get a bit more out of it. Is there a coilpack setup, ignition mods?, ecu tuning that might help...electronic water pump? im just trying to see what all I can do. btw my xb is an auto because I am in traffic daily so i didnt get a stick cuz they suck in traffic. thx!
