Issue with performance once speed limiter removed

I have the following problem with an R33 GTR series 1

I recently put on an Apexi RSM to remove the speed limiter. Now when I go over 200k/hr, the car seems to surge on boost and then lacks power for a second or two, then the power kicks in for a second or two, then back off.

Does this mean that there is not enough fuel and may be in need of a new fuel pump, or has this got something to do with bypassing the speed limiter and needing a fuel cut defender.

Any ideas on this would be appreciated.

Thanks in advance.

I got this exact thing

when i get to about 200km/h is just wont go any further but im only on about 5000rpm, i know the car has another 30-40more km/h to go.

and it doesnt feel like its a cut of any kind, it doesnt really go cut and u have no power, it just sits you there

its weird

      I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as

      Rusty roof repair

      By Duncan · Posted

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      first time swapping rb25det into r34

      By Duncan · Posted

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too

      hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy
