I'm keeping my eyes open for the Pure800 but haven't heard anything about it lately. PS2 would be cool, I've seen an n55 recently hit ~500whp on an e30 BM3 OTS map. A quick spooling 500whp (holding power up top) would be very fun. |

Reviving this thread.
Flashed my 3.5i to OTS MHD Stage 1, noticed the power increase immediately. Super smooth, only other mod installed is a chargepipe. With my laptop hooked up doing some logging, on the stock map I am seeing 8psi at peak and MHD stage 1 12.2psi at peak. Those #'s seem low? I thought I read stage 1 is 14/15psi and stage 2 17/18psi? I have a catless downpipe and NGK 7506 plugs to install, then I'll try MHD Stage 2 |

Can you take some logs with MHD and post them? Stage 1 should be around 14psi I believe but it would be worthwhile looking at a 3rd gear log to see what's going on.

Yup I can make some logs once I'm done the DP install hopefully today. I'm for sure not seeing above 12.2 psi spikes on MHD stage 1, which leads me to believe I might have a leak somewhere.

Got my DP on, gapped NGK plugs and chargepipe. I loaded the MHD stage 2+ and my sport mode gauges now show 480hp / 560tq. When I go wot the highest I see is 370ish and 420tq. Which again leads me to believe I have a leak somewhere? I do not have any codes, the car has been running great, it just isn't as fast as what guys claim a N55 tuned is, maybe I had too high of expectations? What are other guys seeing on stage 2 and stage 2+?
I have a '22 Scat Pack Challenger which is 485hp and it feels leaps and bounds quicker. I know it's comparing apples to oranges but they should have similar bhp and the scat is an absolute boat anchor. |

Those gauges aren't really accurate, but a 3rd gear data log would help determine if things are running right. Stage 2 N55 cars on 93 octane are making about 370-400whp depending on what dyno you go to.
For reference my Stage 2 E50 car made 400whp on a Mustang dyno which equates to about 440whp on a DynoJet.

I am thinking maybe my aftermarket chargepipe is leaking at the throttle body under wot. I have to run out tonight and will pack my laptop to get a datalog. It's pretty disappointing though. |

I had data logging auto enabled, there was a pile of graphs (8) when I got home. Here is one, I have no idea what I'm looking at note this forum didn't like my link, so I had to add a space between . Com - please copy and adjust in your browser.
https://www.compusystems. com/servlet/AttendeeRegLoginServlet?evt_uid=690&_ga=2.10422413 1.2016750239.1666749257-1137408794.1666749257 Did a few more runs tonight, using the monitor while driving it looked like k was hitting about 17psi at max. My 0-60 is pathetic at 6.35 & 1/4 mile I think should be closer to 13.0. |

Bringing back this thread.
Just recently bought a 2018 BMW F15 xdrive35i and it's too slow. I came from a 2018 BMW F30 with the B58 and had the MPPSK installed. Is the BM3 or MHD tune worth it? I miss being able to lightly press the gas pedal to pass someone. With the x5, I gotta floor it to get around someone. So any input would be best. What HP / TQ numbers are people seeing? Thanks!

Anyone?
Also, this morning I was driving into work and needed to pass a few cars and I punched it and talk about slow. After my x5 goes into the dealer this Friday, BM3 will be ordered!

When I flashed stage 1 it was a world of difference, then I bumped it up to stage 2 91 with a high flow DP and it's even more responsive. Well worth the upgrade you will only ask yourself why you didn't get it sooner lol. |
