Weird Fuel cut problem (Very Unusual)

[Xxmarcusrxx]

So basically when I'm pulling in WOT, the injector latency will drop to 2% randomly. I happens usually when i start at a low speed and do a WOT pull in third gear. It almost never happens when i do a pull starting in second or first ( i can do through all the gears without a hiccup). Here's my tune and logs of the problem.

rb25det neo
fmic
blowthrough setup
Q45 TB


I've got a couple fault codes:

both of the throttle codes from swapping to q45 TB
primary ignition fault
boost sensor fault

Change boost limit TTP/TP counter values to 255 and see how that goes

Disconnected boost sensor is probably triggering the early cut

I found this thread while researching a similar issue. My rb25det would hit a rev limit like fuel cut at 5900rpm and would then keep pulling. My lack of boost solenoid was part of the issue, we maxed the tp tables as Matt said ^. After some more hair pulling my tuner figured out that since my speedo is not hooked up, the ecu was hitting a speed related tp limit in one of the tables. He maxed said table out and the problem was completely resolved.

I hope this helps anyone with a similar issue.
