STOCK SR20det bogging at low rpms, help please

[filluptieu]

I have a almost stock s13 redtop sr20, the mods are a complete 3 inch exhaust, walbro 255, 300zx tt fuel filter, k & n air filter, and BOV.

now the car starts up and idles just fine, my rpm isnt working, but the motor sounds like its idling right where its suppose to. now whats going on is when i accelerate from stand still at low rpms it boggs but after about 3 seconds of steady acceleration the motor boggs a bit and then accelerates and boost just fine.

Now this seems to happen at every gear and is pretty consistent at low rpms. But keep in mind right after it happens she boost/drives just fine like nothing is wrong.

Any suggestions?

Also how would you know if the ecu is screwed up?

similar but it does not bogg as bad as your kouki, I boggs but will take off and give full boost weither low acceleration or high acceleration. Did you figureout what the problem was?

Also how can it be a vacuum leak if it idles correctly?
