Hi to all,
I have a problem and I don't know how to proceed...
I have a 2015 86, 45k miles, HKS supercharged by 4k miles. Since last week the car was working fine without any problems, I use it as a daily with 1 track day a month (full day or a full weekend).
Recently I have a strange issue, after changing gear near the rev limit in wot the engine stops climbing the rpms for a second and if I keep my foot down eventually the rpms start increasing again.
This happend to me like 4 times, it's not persistent.

My engine modifications are:
-Hks supercharger
-Hks oil cooler
-Hks spark plugs
-Avo 3 bar MAP sensor
-Hks EL headers with cat (GT Spec)
-Milltek overpipe 2,5"
-Custom front pipe 2,5" no cat
-Custom catback 2,5"
-Greddy oil pan baffle
-Ecutek Tune

Stock injectors and fuel pump. I think the problem is mechanic because since last week the car was running fine, the only thing that has changed is the external temperature (like 35°C) No CEL or whatsoever.

Here is the log of a 3rd gear pull

Here is the log of the problem, 2nd to rev limiter, change to 3rd gear, back in wot, rpms stops climbing, i keep my foot down for a couple of seconds until the car starts pushing again and after that I stop accelerating.

My tuner unfortunately it's not available until the end of the month and I want to have other ideas about what the problem might be.

Sorry for the english, It's not my first language.
