ESS vs BM3 tune
So I've had BM3 stage 1 on 91 on my previous x5 50i and it was totaled so I bought another x5 50i and was considering either doing BM3 again or ESS tune. Anyone had both and noticed a difference? I know ESS is like 200 dollars more then bm3 but if that's what turns out to be better I rather get that. Please let me know thank you!
