tuning tips

I have a sweet 2.0 gti and need some help on getting a little more power. It has a cold air, chip, and exhaust already. I want around 170 to 200 hp. I am on a very limited budget. If it is not possible to get this much power how much is possible. Also how much do you think I have now? The cold air is AEM, the exhaust is magna flow, and the chip is a p-chip.
Thanks

hahah, 170 is even laughable with a limited budget, unless you know how to bore out blocks and have access to free overbored pistons...
yer best bet would be to get a cam, a cam gear, dump the p-chip and get one from Garrett or from someone that doesnt also mass produce parts for honda's...
after that, drop it to the floor with some KW or FK coilovers and be happy you have a semi reliable car...because without a turbo or some seeeeerious head/block work, you'll never reach 170...
my buddy has a 2.0t with forged pistons, flowed head, new rods and connectors...everything inside this motor is new...running a t3/t4 hybrid at 13 pounds through an intercooler and still only has about 180/185 to the wheels
