Solved. Car is cutting power at 5k rpm WOT

[S4MYO]

Hello all,

My 2018 civic si is seems to have a new issue of cutting power at 5k when I’m kinda getting on it. It’s like when I try to do a pull it cuts me off and the redline starts flashing.

This was never an issue, I just got it back from a clutch install so idk how that would have caused this.

It happens in all gears, but I can go past 5k if I don’t floor it. No error codes are given either. And it’s not traction related. I haven’t changed the tune recently so idk what’s going on. Any insight would be appreciated. Thanks!

Mods are:
Hondata (base map tune)
PRL cobra
PRL flex fuel (didn’t have e85 at the time)
Hks exhaust
Rk6 clutch kit

Solved. For whatever reason when I removed full throttle shift with Hondata the car was back to normal. IDK why the aftermarket clutch would cause an issue but all good now.
