Wont go to rev limiter above 7k

[Bvillarreal]

I dont know if it is something in the tune or mechanically, but when the rev limit is set anywhere above 7000 rpms it does not engage a rev limit it just feels like it drops off. I do not have my wideband connected to my s300 so i cannot provide a datalog but here is my tune and a video. Fully built LS/Vtec 15 psi RC 650cc, garrett gt30. Using NGK BKR7E

This is a video where my rev limit was set to 7800. as you can see it doesnt wanna go there

Any help is useful

What are your spark plugs gaped to? What type of ignition are you running?

[Bvillarreal]

Ngk 8s gapped to 25, stock ignition. I've tried ngk 7s also and nothing, I've also tried gaping at 28 &30

You need to post a datalog showing the problem.

[Bvillarreal]

I don't have my wideband hooked to the s300..

[Spunkster]

You can still datalog.

i'm having this problem on my b16a as well. It won't rev over 7500rpm. Any idea?

Thanks

[Bvillarreal]

I will post a log after work spunkster

[ONGDATA]

maybe its the boost cut bro

[Bvillarreal]

Feels nothing like a boost cut though. If it were it wouldn't only do it above 7k?

[crucian]

Is the engine breaking up when it tries to go over 7k? or is it just shutting down?
