Does the UPD really work?

Is it a worthy modification. Will I notice any power gains that can be felt?

Thanks

YES. Mike, I got better dyno numbers with the UPD over the K&N FIPK to the tune of 6rwhp. I'm sold on it. Almost everyone I know that got one noticed the improvment almost imediantly. Plus, they may help you milage a little. You just missed a GP on them. Where have you been?

I installed mine about two weeks ago. Can't back it up with any numbers, but a definite SOP difference. Gas mileage seems slightly better. Well worth the GP price.
