$1500.00

You have to weld a bung holeo (couldnt resist :p ) to your exhaust pipe for an o-2 sensor and do some wiring. I dont know anyone with it other than Chad's friend Jim, and he has the efi with the turbo (sick, sick man)

$1500 for just the throttle body or does it also include the fuel pump and everything else you need to install it? I really like the way it adjusts fuel rates on the fly.

Everything. I heard its not as easy to tune as one might think though. I have no experience with it to confirm that.

I cant see a trx450r engine with 85-90 horsepower living too long. Obviously must have some sort of clutch lockup or something because i can feel my clutch barely holding up to my 60 something horsepower motor. Even the trans cant be too happy about that. There will be a list of weak links popping up one by one with that kind of power.
