I was about to ask why you were still running a VAFC if you had a p28 that's already socketed for a chip. Most of the chips out there are shit. There' s a reason why you tune on a dyno, because different, climates(humidity, temp), elevations, and car setups respond differently. A generic chip, even if it is a "spoon" or whatever else is not going to get you what you should get out of the setup. Most of the Ebay "performance chips" even ones that are labeled spoon or mugen will not make anymore power than a standard ecu. It's not that much to get a tune from Scotty through Mainstream using crome. You won't have to buy anything if it's already socketed and setup to accept a chip. He can put it on the dyno, use a base tune that will be close and dial it in, for 200-300 you can have your car maximizing it's potential. I agree that the next step is to get a set of cams such as a pro1 or m22x but if you do that you better get it tuned with crome. Also invest in a quality header. The setup you have will be fun in a hatch if it's something new to you. Take your time and spend your money wisely on quality parts the first time instead of buying cheap and having to replace it later. good luck
