full boost @ 4000 ey...

how was this measured?

I have found that you can get quite different results depending on how it's done.

Floor it in 1st from a rolling idle start and it will be slow to build boost. Floor it in 4th from 60 and you should hit full boost earlier.

If you did the test the first way, 4000 is about normal. the 2nd way, something is a miss with the tune or your FMIC piping. What type of kit is it?

Flooring from 4th should see you hit about 1bar around 3000-3500rpm if well setup.
