Hi all,
2011 zx14 with PC3, CT single and Brocks street map, I am very happy with the CT but was somewhat disheartened with the major "Pop" on decel at approx.3.5-4k. I found DogoZX's map that he posted, (http://www.zx14ninjaforum.com/messages.cfm?threadid=343DADB4-D56B-84E2-1332CC599F3A8F4B)installed the map and it has greatly reduced the major "pop". I have some minor "pops" but nothing like the big "pop". I am at roughly 55 feet above sea level, so I think the Brocks street map was too rich (by no means am I trashing Brock, his products or maps). First gear response is crisper and the bike pulls extremely hard through all gears.
I know nothing beats a custom tune, but for me DogoZX's map is pretty spot-on. I think the shop where DogoZX had the custom map made is roughly 120-130 feet above sea level.
