Whats the Rev limiter on a R34 Rb26???

I just bought my r32 gtr a little over a week ago and it has plenty of mods and Im trying to figure out everything that could possibly be done to this car that I dont know of. Heres a link to the car with known mods

So one of the biggest questions I am having is I have no idea if the block or head is built at all and the main reason im asking this is because I honestly do not think I have a rev limiter. She pulls SUPER hard and fast from 5500+rpm and before you know it im at 8k rpm and need to shift. Well today I kinda went too far and it hit 8500 and still no rev limiter (im not trying to rev it high it just goes from 5500-8k within a second or so and im still not used to the power). This is a chipped ECU that i plan on ditching within 6 months for a Haltech, but right now im confused. Was this motor possibly built to go 9k revs or something? I highly doubt whoever ECu tuned this thing would remove the rev limiter.

I currently want to buy a Zeitronix wideband data logger system and a Bee-R just to get me by for now so i dont blow my engine but at that point I might as well save up a bit more money and just go Haltech which will do both of the above with loads more.

Your thoughts?

Stock limiter is 8000rpm.
How come you didn't find out all the details of the motor before buying?

I don't know about 34's but 32 tachos like to "exaggerate"

Who ever chipped the ecu could easily have disabled the rev limiter or raised the limit. Hopefully the engine was fully balanced but can you not find out from the previous owner?

Im in the USA and the car was bought from japan so no way of actually knowing what was all done. I know a lot of the stuff but this one is weird. Having a huge T04R turbo wouldnt it be weird to raise the rev limiter to an unsafe spot by the tuner? the power never falls off and keeps going.

are the r32 clusters known to be off at high rpm?

Well built RB26 engines are sometimes revved up to 10,000 rpm.  With the proper tool I would have thought that you could interrogate the ecu to find what rev limit it is set to.

Used to rev my 33 to 9500

Don't bother getting a bee r rev limiter, they are rubbish.
Take it to a tuner and just get them to check it out. Also if you are unsure, play it safe and don't rev this shit out of it until you get it all sorted
