Thank you so so much!

This might be able to help out quite a few 2.5i owners looking to fit a 3 stage manifold (I've seen a few posts on it in this thread and other forums).
Btw you can try flash 2.5si transmission as well, maybe there's difference.

Set the protocol to KWP2000 in winkfp before flashing
