I just had my car dyno'd and found I lost torgue low down but gained power at the top of the rev range. I checked the presure switch,and found that it was coming on at .3bar. Could this be my problem? I have set it back to .5bar and going to dyno again. Any thoughts?

If your spray to soon then you can be bogging your engine a bit, That's why doing a dyno is a good tool to tune the vehicle.

One more thing have you reduced your plug gap yet? That's one of the things that is important on most vehicles.
