Why is my fuel cutting out?

[dsmdrew07]

I have a 1992 Eagle Talon. I have a 20g turbo, stoker kit, 650cc injectors and my fuel cuts out at 5000 rpms sometimes in the 4500s. I used to have 450cc injectors and i upgraded to 650cc's to see if it would help but it still cuts out. I have dsm link and tried to tune it and up the fuel load at higher rpms but still it cuts out. I am not sure what to do.

First thing, please make a vehicle profile and post a log. You can post DSMLink logs by clicking on the Add Photos button and select the log file instead of a photo.

Then pressure test the intake and make sure there aren't any boost/vacuum leaks.
