Rev Hang Issue on Tephra V7 on Evo 8

Hi
I got my JDM Evo 8 GSR tuned recently on Tephra V7 and I'm having a rev hang issue during high Rom shifts. When I go to shift and press the clutch the rpms shoot up around 500-1000rpms or so.
My ROM ID is 96530706
I Have attached my tuned ROM file below. It would be very helpful if someone can take a look at it and let me know what could be wrong

Thanks in Advance

So will the values need to be same or does it differ from car to car?

@Boosted Tuning will you be able to take a look at it?

Thanks in Advance

if boosted is tuning the car.. .just let them fix it.

this just reduces the iscv from messing with the air flow ... which is why it is rev hanging..
its staying open too long when you let off the throttle.

wont hurt to try it.. flash it.
if it doesnt work, flash it back to what you have now.
