Once again thankyou for your prompt response. It would be just great if you cud send me the pics marked with arrows. I have a Ashpec ECU, do I have to remove the boost jets?? Do I have to disconnect the stock Boost controller?? I have sent you a e-mail with attachment of a diagramm I think it should be according to your advise. I could post the diagramm here cause I do not have the tools for it. Look forward and cheers, TR
