Appreciate it s346k. 1st time I’ve heard bout that as an option. (Stock air box mod). It seems e85 n more airflow is the best bang for your buck. 1k to 1500k vs 3 to 4K FBO. All for a few 20 ish horsepower. Wouldn’t a better throttle body make it more snapping more so than dyno hp. I had bad luck with a ported TB on my gen 2 CTSV.
