Well, proper tunning is a relative term. From the sounds of it, wihtout some sort of adjustable fuel controller, or cam gears, you don't have anything to tune..... But the average tunning session runs about 80-120 an hour, with most simple fuel computers taking about an hour or two, and more complex standalones taking up to five or six.

As far as mods to maximize performance, Cams including the rest of the valve train is a good performance mod assuming you plan to stay all motor, and higher compression is also a good one, usually acheived by getting higher compression pistons.....
