Default b16 swap poor/no acceration in vtec

b16 swapped vx hatch, just got the swap running semi well. When I accelerate through the full rpm range it feels like it has no power, and once it gets past vtec crossover it accelerates even slower. it's like it's hitting a wall in the power band.. not sure if it's timing or misadjusted distributor.. any advice guys?

Remove the oxygen sensor and run it. See if it runs better.

o2 was deleted and substituted on Neptune for my test run, could my firing order be wrong as well?

If your firing order was wrong it would barely start/run and would most likely kill the coil.

Did you check mechanical and ignition timing? Check engine light on?

it was my timing guys. intake cam off by a tooth and exhaust was off by a tooth and advanced a tic on the adjustable cam gears. always always always check the timing if you didn't do it yourself! thanks for the input!
