fuel pressure reg.?

[drdon51]

Ive got a big hesitation in every gear between shifts even with moderate acceleration.I had someone to do a scan and they said my car was running lean at mid rpms, Is ther an adjustment you can do on your fuel pressure regulator? Any suggestions?

A custom tune on the computer done on a dyno by an experienced shop can change that -if the problem isn't there at full throttle for example-then fattening up the mid-rpm would cure it- not higher fuel pressure(IMHO).
