How to tune it?

Now i had the base pressure set at 3.8Bar and turn out the engine runs horribly rich....

On highway drive on top gear when cruising,the engine is run horribly rich when on part throttle and cause jerking,even when WOT it is still rich as the engine like having no pull/feeling heavy+black smoke behind.....

FYI the engine is a L9 Turbo,running SR20DET pump and a Tomei FPR,other then that all is stock ~

Need help from u guys before i get it too lean and blow it...
