BM3 E30 tune compared to Stage 2
So i’ve been running BM3 E30 Stage 2 tune for over a month now and i’m on the edge about it honestly. I feel as if there’s barely any difference from the car since it was already Stage 2 prior and it also has less aggressive pops and bangs because of the ethanol. What do you guys think, better off just going back to 91 Oct. Stage 2 for the convenience?
