i have a hondata 2b with p28 ecu, has boost option (fully tunable fuel & ignition tables under boost), adjustable rev limiter, adjustable vtec actuation point, and shiftlight. 550 firm. System works great, selling to try new standalone system. Hondata stage 2b can only be tuned by a dealer or stage 4/ s200 user w/ ROM Editor V3 software.

for 550 i hope you have some options on the piece-
