Hey guys... i have a 97 JDM ITR motor in my eg hatch... just recently put in Skunk2 stage 2 camshaft, springs and retainer, also tune with Hondata 200... the problem is that when i throttle at high speed, in 5th gear going into 4800 rpm where vtec kicks, it chokes... it runs fine and strong all the way to the point where vtec is suppose to kick.... what's wrong here... 1st, 2nd,3rd and 4th, vtec kicks in flawlessley... it's just when i'm in 5th gear driving normal, and speeding up to pass slow cars... chokes at 4800rpm, and wouldn't let me any futher than 90-95mph... HELP a FELLA OUT... THANKS IN ADVANCE....

EDIT: BTW I'm using a P28 ecu

 

i have a very similar problem in my b16 ef. and when it does it my cel22 comes on
i know that it is for oil pressure..but it confuses me because it always does it in fifth and sometimes in fourth...id say check your oil level..what is yuor a/f when going into vtec?it might be the tune.
