Just finished putting the MKTurbo kit on my car. Im having an issue where I get to 5k~ rpm at wot and it cuts out. wot is fine in 1st gear but any other gear it struggles. Don't think its a fueling issue I have 640cc injectors. Any recommendations would be appreciated.
Also here is a link to the datalog https://easyupload.io/g3fzvm (file was too big to upload here)

I don't have access to check the datalog right now, but I would check and see where your boost cut is set, sounds like that might be causing said issue.

First, wire open the wastegate, then do a WOT pull. Take a log and see what you max KPA is. Make sure it is not more then 105-110 or so. If it is more then you are creeping and need to port a bit more.

I am guessing you are possibly creeping a bit and hitting the boost cut. I won't have time to look at the log until late this weekend.

this is happening with the wastegate wired open. Im making around 140KPA so clearly i still need to port it more, but my overboost protection is set to 170KPA so its not that causing the issue.

I believe that isn't necessarily true and is probably a combination of the two. Someone correct me if I'm wrong, but I thought I had read and understood that even if you don't hit your set overboost protection KPA, if the Megasquirt "predicts" that you will (eventually) hit it based off of the RPM and KPA curve/graph then it will still kick in.

Correct, but it should not do that unless you are within like 5kpa or something. Not 30kpa below it.

I don't see any sync losses in the log, but you've got some increasing timing errors as you approach 5k (+/- 12.5) (yellow line)
