RB25 s13 rev limiter issue

[JohnDanyal]

So ive been having an issue with my rb25 rev limiter and i cant seem to figure out what the problem is exactly. pretty much the car will pull amazing up until redline but it will not bounce off the limiter, instead and it sounds like some sort of soft cut but it will bog the car down until i let off the throttle. if i get back onto the throttle it will pull up until redline again and do the same thing over again. ive replaced the fuel pump (walbro 255), fpr, fuel filter, spark plugs (gapped to .08), and ive checked the coil packs and they seem fine, ive also replaced the ecu, maf, and coil pack harness with known good ones and it had no affect. this issue has been happening since i completed the swap in january but randomly went away and it was bouncing off the limiter for about a month or so but then it started happening again recently. also the wiring was done by an extremely reputable shop so its unlikely for it to be a wiring problem but who knows. someone plz help

RB's use a soft cut for the revlimiter.

this is not a rev limiter. like i said it does not bounce like every other rb, it bogs down right when it gets to about 7200 and will keep losing power and rpm until i let off the throttle and get back on

probably cause your plugs are gapped too .08

Ooops I meant to say .8mm not .08

What plugs are they? Might wanna try gapping them closer to .025.

[JohnDanyal]

They are BKR6e's. I'll try regapping them. I'll try anything at this point
