Car is still in the shop at RT Tuning. They have been in contact with Aaron so we'll see how it goes going forward. I was also told anything above 600whp on 93 might see some detonation. My goal was 625wph to 650hp on max boost but if we can't get there, I may be looking into methanol injection. If anybody has any thoughts or suggestions, I'm all ears. Thanks!
