Any performance shop should be able to do the IPF SC kit install in less than 2 working days. I was quoted $500 for install and a before and after dyno. This is a straight forward install I did with the performance shop and I know others who have done it themselves.
This is for the SC kit, I saw you mentioned twin turbos, didn't know the even offered that ?
