Default Car bogs under high rpm/boost. Sometimes.

Ok well it happenes every once in awhile , but yesterdays case ; i was in 5th gear at about 3-4k and my car started to bog. felt as if it was mis-firing maybe?? Im just not sure what else it would be or how would i fix that problem. If it is misfiring should i retard the timing some more?

I was having a problem like that. My ignition and fuel tables didnt agree at 5mmhg vacuum, which was about the rpm you said. What management are you using?

I thought if you used a VAFC you ditched the FMU, but id get it tuned. Where is your vtec engagement set at? That was another part of my problem, it was actually a hondata glitch with the vtec changeover keeping the pre-vtec maps or something.

I belive you ditch the fmu when you use the vafc hack. with the dsm's.. But right now my Vafc Cor: is set to 0% all across. my vtec i belive is kicking in at 5k RPM

I had similar issues. Turned out to be fuel pressure. Cranked it up a little, and voila!
