check out some of the site sponsors. some of them may even be members that can direct you further (doubt that they will find this thread though). also, since they are a sponsor of ME, i highly doubt they would do anything shady. word would get to the site in a heartbeat.
im sure someone on here can provide additional info about the specific ones you may want/need.
id start with the CAI, get the tlok and gears together, chip and tune. i believe the gears also will throw off your speedometer, but the chip can re-adjust that.
start small with the CAI first though
