Ok im from El Paso TX. There is literally no place to get a good custom tune. So I figured I would give this guy a try, only $50, the "Jeffo" maps. Like described in this thread--------->http://www.zx-10r.net/forum/showthread.php?t=85559&highlight=jeffo+map . The map looks wierd, like nothing ive ever seen. I honestly look at the mapping in the PC program and I have no idea what im looking at. Could someone possible look at this map and tell me if its garbage??? I could email it to anyone who knows what their are looking for. My mods are M4 GP Slipon(baffle in), secondaries removed, BMC air filter. and the temps right now are from 60-80degrees with very low humidity and im at 3500 ft above sea level(if that makes a difference).
