i'm thinking about putting an AEM Adjustable fuel pressure regulator and turning the fuel down, but i don't know..
Also when i Rev to 6000+ rpms and i push the clutch in i hear a grinding noise.. but this is the ONLY time i hear it, when i'm engaged in Vtec and revving past 6k Rpms and i push the clutch .. i'm thinking maby pilot bearing ? because i can engauge vtec and shift at 5.5k-6k and it wont make the noise... what could this be ?
And last but ot least, my tranny has a nubby grind in 5th gear.. it ONLY happons if your revving above 3k and shift into 5th.. below 3k it wont grind.. is this just a syncro going out ? is it easy to repair ? is it worth it ?
PLEASE if ANYONE can think of ANYTHING that might help let me knoW!!

Get rid of the P14 ECU. That by itself should fix a lot of problems. In order to troubleshoot the car, get rid of the VAFC and start with a stock engine management system. Don't buy an FPR.
Start by getting the right ECU for the car. The P14 and P13 have many differences in their maps.
Also, you may have a bad injector or misfire in one cylinder. I would check that after you fix your ECU.
