yes, you can do it yourself and yes, you can screw it up yourself if you're not careful. Some amatuer tuners have destroyed engines while messing with the tune. All I can say it be very careful if you do it yourself and definitely buy the O2 interconnect cable so you can watch the tune and not lean it out and burn your engine up. It's worth the extra money for peace of mind.
ya what he said, plus when you add up the cost of a laptop and the cost of HPtuners compared to the price of a good dynotune ($350) I'm not sure it's worth it. Although it would be nice to make adjustments for future upgrades.
