Does anybody know why Hondata limits the RSX to 7300 RPMs and the EP3 to 7700 RPMs? I know their intake manifolds are different but the RSX is running on the shorter runner during high rpms anyway. I've called and asked a few shops that sell Hondata but they don't have logical answers. They're esentially the same motor except the EP has EPS (Electronic power steering) and a single runner intake manifold. I emailed Hondata but was just wondering if anybody knows. I'll let you guys know what Hondata says when they reply.
