I've done a number of clean logs at 17psi, no issues at all, all clean. Have upped the boost to 20psi and the car runs good up to between 4500rpm and 5000rpm and it has what I'd call a hic cup. I've done a number of logs and I've attached one that includes one run. The IDC drops from 80 to 40 and I get a lean mix. This has never happened on a 17psi run, but has done it every time on a 20psi run.

The injectors I bought 2nd hand from a URABUS WRX and are 565cc which fit straight into my Airtrek which cames factory with 450cc High Impedence Injectors. On the 17psi runs, I've got these at 95% IDC, so am looking at an upgrade again. Probably FIC 1100cc at this stage. Any ideas on what could cause the lean mix?

If anyone would like to make any suggestions to what they see in my log for tune, by all means do so. I'm still learning
