I have put on the easy 3 bolt ons (aem air intake,cherry bomb exhaust and pcm) and I am now looking for another mod to get the extra hp. I am thinking about either a cooling fan or another chip to go along with the pcm. Does anybody know which ones would get the most gains?

Get a turbo, it will make the most HP.

Gut your cat- easy 10 ponies there and Dyno proven

Denso Iridium ITV16 good for gas milage and throttle response

4.2 Throttle body more air and better throttle response.

you are thinking of a throttle body spacer he is talking about a throttle body. i duno if you have a i4 or a i5 but you wont see any gains with the 4.2 on the i5

I am planning on doing that at the end of the month once my tags expire. Does putting in a Jet Servo help the 1/4 time any? I know that it doesn’t help hp but I was thinking it might make things run a little smoother

I've heard the Corvette and JET servos help out, you may get a little sideways in the rain according to some (under heavy throttle)

I just passed inspection and I was wondering if anybody took out both their cats and how much gain that was? I understand it will be loud but it seems like if the first one gives you 10hp the second one would have to at least give you an extra 5?

Any transmission specific shop can (should) be able to do it. Look under transmission service in the Yellow Pages.

Alot of people install this in their driveways. A transmission shop should have no problem. What were you asking them specifically?
