Well im trying to decide how I want to go about cleaning up my top end smoke. How much boost can a studded head take? Are compounds doable and safe at my levels (50 psi on single turbo). Is nos or propane viable options? I'll update my Sig but current changes are a s475 turbo. Changes to be made are swapping my full cuts to .024 delivery valves and possibly changing my 5x20s to 5x16s or 5x18s if I can't clean up the top end smoke. Just looking to gather thoughts and opinions to make an educated decision going forward. Plan to keep truck somewhat streetable. Not daily driver more Sunday driver or cruise down to the occasional car show. Thanks for sharing your knowledge.
