What would you get next?

I would like some more performance in my car for less then $300. So far I have a 4th gen 5speed with a ypipe and intake. I was thinking of either getting a b-pipe, or an underdrive pulley. I might also want a Gtech pro. Does anyone know if the Gtech pro is good. I kind of would like a good tool for giving me hp estimations, and track times. Or do you think the Gtech is just a waist of money? Which of the 3 would you get? Oh and I am waiting a bit till I get an ECU upgrade.

my self i'd say b-pipe finishing up exhaust would be a good idea.

The G-tech is a decent investment and is fairly accurate. It's not a hundred percent but it will give you a pretty good idea as to your 0-60, quarter mile times, and a general hp rating. Just look around the net for pricing as I've seen them vary in price by a hundred dollars or so. It does nothing performance wise, so it's a matter of personal choice in getting the gtech or spending that money enhancing your performance in some other way.
