It's just the nature of how the MHD OTS tunes are setup versus how BM3 OTS tunes are setup. MHD doesn't intentionally overboost nor does it allow overboost without some throttle closure intervention. You can also substitute "exceed load target" for overboost in that sentence. In contrast BM3 OTS maps allow and even intentionally overboost in the lower RPM without throttle closure. At least for EWG for sure. Need to look at BM3 PWG logs to confirm. But in any case it doesnt mean one is better than the other for tuning PWG - that would imply one is better at actually controlling the boost, not simply allowing it to overboost without throttle closure. I am sure the MHD behavior could be adjusted with a custom tune if so desired |

I think the key thing here is this is just default OTS map behavior on MHD/BM3. It doesn't mean you can get a tune with different behavior, such as decreased sensitivity to overboost or raised overboost thresholds. The whole 'exceeding load target' aspects is not really relevant to BM3 in the first place since they aren't tuning based on that. And again, some people might want that stock-like overboost/overload protection in place, even if it means getting some throttle closure at times. From my experience these small throttle closures in MHD are imperceptible in the car, and you dont even realize it until you see the log. |

My personal opinion is that a target is there to be matched - not exceeded. Another way looking at it is that, if targets are exceeded then some safety measures must have been relaxed to some extend. When I ran BM3 2H i sometimes saw 23psi with a target of 18 - WITHOUT throttle closures. That was the direct reason for my switch to MHD. Now 2 years later it seems that this is still the preferred strategy.

PS: Here we are ONLY talking about the OTS maps. With a custom tune it is all up to the tuner what approach he want to take.

Also, the bm3 ots maps have evolved a lot in the last two years since this guy decided to start trying out mhd. Also, some of these posts make it sound like bm3 is somehow completely unsafe and allows crazy overboost that can damage your car. This is untrue. Sounds more to me like a couple mhd fanboys trying to see who can sound smarter.

This has been super useful. Thanks for all of the input!
I think I am going to go with MHD. The idea of tunes that are tuned based off of load vs boost makes me feel better. |

I'm leaning toward Fabian (Pureboost) for a safe tune... seems others just maxes targets...

Hey I’ve been following your responses on many different platforms regarding the n55 pwg. Just wanted to know if the upgraded ps2 turbo helped with boost in the high rpms as the stock pwg obviously can’t hang

You replied to a 2yo post to say that? What? Please God don't be another scammer about to post in the for sale groups.
