what you described as a redline is a fuel cut... redlines are where an engine stops making useable power.

many manufacturers put fuel cuts just above the redline because there is no point to go any higher, and you are most likely just hurting the engine.

what i was asking is if the engine could go higher, and it can. just making sure of the strength of the engine.

now the speed limiter does the same thing, only it cuts at a certain rpm that coincides with a certain speed, if it doesnt know the speed i think it's just cutting because it thinks there is something wrong or it doesnt want you going to fast so it just cuts you off in all gears.

vtec doesnt kick. look at the torque curve of any vtec enabled car... the torque curve (the power you feel) stays relativly equal on most of them (on certain engine, most specifiacally the type-s engines of the 02-04 years had their vtec point set a little off from optimal, so the torque curve would begin to drop and then came back up.)

i'd say figure out how to fix the codes the engine is sending you vs just getting rid of them.
