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?

 

Right now its untuned and using a VAFC with 12:1fmu, stock injectors.

 

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!

 

maybe you lean out under lots check the gap on your spark plug gap maybe the spark is getting blown out
