I was enjoying the bms for awhile but as of lately it seems to be hesitating and stuttering? I'm in the process of switching over to mhd. I'm hoping the stuttering issue is the piggyback. Car has new coils and plugs with under 10k on them. Was wondering if anyone else ran into stuttering problems hesitation at higher rpms running bms s1? Not even sure it's the piggyback? It's almost like fuel is being cut? No codes or cel?

Unfortunately, it's probably not a piggyback issue since it ran on the car fine for a period of time. You'll need a tune that can datalog to diagnose the issue

Yea I’m aware it may not be. The tuner was used when I bought it. I’m taking it to my mechanic to diagnose. It almost feels like a fueling issue. I’ll update here when we know the culprit.

Not yet we're taking it in on the 19th. Car drives fine most of the time but does stutter when maxing out. Currently running redline fuel system cleaner through her but have in the past to maintain. Car has 90k miles. I def will update when fixed.
