hey zach, glad to hear your kits still doing well and pushing some more out. hotbox, sorry to hear that your xb wasnt up to snuff for you, but like vetter, i am very pleased with my turbo'd xb (though it isnt zach's kit he gave me alot of advice and encouragement) My entire setup is custom, and that could be the difference, but at 6.5psi the little cars almost faster than it needs to be, almost haha.
