My thought is to just dial the tune back a bit. Not looking to set records but if I can hit 600-650 awhp on race gas without P.I. I’m good.
I am XI so DB shotgun is out, not sure about the single barrel though.
You probably won't need Single barral if you're HPFP is healthy. You can definitely make 600-650whp on race gas however with the single barrel you could probably hit around 800whp since the barrel is rated for 600whp on straight e85.
