We just finished a Stage 1 kit from Sal at AcePerformance.com on my 2012 ZX14R and all I can say is WOW! Before the kit I had a Brock's short meg full system and a flash and tune and the bike ran 193mph in the nine tenths. This was with mirrors and a Spiegler handlebars that stick way out. After the Stage 1 the bike with a Brock's CT system ran 205mph with the mirrors and bars and on pump 93 octane gas. Sal really knows how to port a head and tune for max power. His "Real World Tune" is incredible as he tunes for the full effect of the ram air at the top of 6th gear. Kudos to Sal!!
