Again let me stress the client (who we also sold his kit for him) DECLINED support! There is NO issue with the product and single turbo applications. We have a clients car in house that is making power to 8300rpm on a stock 370z motor...

For those reading this thread we offer full tuning and client support with all of our products. We stand by them as we use them on our personal cars and test them rigorously.

Thank you,
