For sparco, nrg, braums (examples) seats, is the oem seat belt fine?? Or does it require a harness?? My supra isn't a daily. I take it out occasionally for some rolls, at the drag strip, some car clubs autox, and cruising around.
IMO. I disagree, I feel there are better tuners on bm3 compared to mhd. Everything you said on mhd is exactly the same on bm3. Op will have to do research and decide between the 2. My bm3 e50 tune is AMAZING but I haven't dynoed yet.
After my experience, I think e50 on mhd or bm3 should be enough for most people. I just went bm3 with e50 and it's amazing. In a couple of years, I'll probably push for more hp but not anytime soon. Only paid $2300 total for mine.
