11psi fuel pressure or boost? If it's boost are you hitting boost? If you hit boost than that's your prob: honda map sensors dont like positive pressure, and it wont deliver any extra fuel to compensate for the boost.

LOL.....ssshhhhhh your funny

what engine managment are you running

if it sounds like a wrx, are you getting spark to all the cylinders?=spark plug wires not making contact or not getting feul in one of the cylinders. Check

Does White smoke come out the back?= blown ringlands

narrow the search down to which cylinder is misfiring buy starting the car and listen either at the spark plug for the spark or take out each injector plug while it's running. pulling the good ones will make it run worse and that can eliminate that cyclinder

then you can do a compression test.

X2

you can also go buy a NOID light set and put those on the injector clips to make sure it is getting power should you find one that appears to be malfunctioning.

I have adjustable cam gear, and only the intake gear is adjusted. is this reasonable, shouldn't both be adjusted slightly? Just a quick question, it feels like the timing is off but everything adds up.

yeah man, spark is good, and the injectors have an excellent spray pattern.
