I wasnt sure wether to post in 2nd or 3rd gen as I have a 13b-re tt in a second gen car, not sure if its motor or driveline. I ll explain my problem.
I have no problem hitting high rpm in 1, 2, 4, 5. But in 3rd gear always around 5.5k rpm to 6k rpm it will feel like it stops dead in its tracks, almost like a cut. If i give it less then wot then it is okay.
I run a 12-10-12 boost pattern and only get a max knock reading off the apexi of about 30.
Anybody have any ideas as to whats going on or can point me in a better diagnostic direction? thanks in advance.

 

thinking it could be something to do when the second turbo comes online?

 

How often do you hit high rpm in 5th gear?

 

hahah not that often, to be honest ive only ver checked the speedo at 250km an hour never thought to check the tach

 

What's your boost when it stops dead?
