Was the car tuned on a dyno ?
Do you have a wideband oxygen sensor on the vehicle ?

you must be hitting some kind of fuel cut. what is your afr's at full boost?
I had that probelm when I was too lean up top.

Get with who ever tuned the car. You didn't really provide us with a lot of information on the setup so we can't really tell you where your peak power is going to be.

aite so i did some more research and my car threw a CEL at around 6300 6500 rpm it,s CEL #22 the vtec pressure switch ive read somethings about oil flow mainly i found people having this same issue mostly in ls/vtec mine being a mini me i thought ok maybe i need a vtec oil pump like you do when you do ls/vtec but on mine the oil pump is the same one for dx/ex models ive checked my oil level its good changed my pressure switch and triple checked the wiring still i have this F***ing code please help ........................

when my buddy was throwing the vtec pressure switch code it was from his uncle(a professional mechanic of 20+years) over torqueing all his camshaft bolts and that caused the metal to shave off...which lead to the screen of the VTEC solenoid getting clogged up with metal shavings....i would say take off the VTEC solenoid and see if its clogged up

Is your speedometer working? vtec could be set to engage over a certain speed...If vtec isnt engaging that why it feels like a rev limiter...ecu is giving it the fuel to get into it but there car isnt...

Ubertec
