Theres enough room to sping my d1sc to 7k, probably enough to 8k actually,only reason im going to 5.9 now is cause im floating the stock valve cause of the seat pressure of stock valve springs. I forget what my timings at, but nothing was pulled because of the boost car tuned safe at the 20psi and 93 octane.
