I like the HEX stage 1 flash. I had the jb4 stage 1. Feeling wise. It feels twice as strong as the jb4. all people talk about is bm3 and hex. I chose hex because it sold me on, engine reliability and longevity. I wanted to push my car's limit with a tune, that was on budget and that made me feel secure. GO HEX. no regrets
