Its just as I described , I guess my porting makes a big difference . and this may even improve ' cause I am running with my boost controller switched off , so I am sure the waste gates begin opening before the 8psi is reached . I am going to replace two of my 850cc injectors with 1600 soon , then i should be able to use my boost controller and raicse the boost .
I forgot to mention , the diameter of the dp is 3.5" .

 

Thanks Marcel, the info is appreciated...Max
