Looking at our HPFP, it looks very similar to the N55 ones. So I would expect something like the XDI HPFPs shouldn't be too hard to adapt to a B58. |

Decided to gap stock plugs myself (3k mi only) per Alex recommendation to 0.022. Took time however, since it was a pain to get to the last coil which required to pull tower brace, plastic covers, foam thing, etc.
Flash process is easy (I'm technical) and straight forward as described perfect on page 1. The end result is complete satisfaction running on Stage 3 DME and stage 1 trans tune with stock downpipe, exhaust but 93 Shell! Highly recommend. I might dyno in August on independent Dynojet running x-drive.

I’d like to, but it will be a while until temps drop around 65* (95* + now ). I’d say comes October I’d hit Union Grove 1/4 mile strip up in WI.

First custom pump has already been installed and ran in our car. We were able to get about 10% more fuel volume out of it, which is a decent improvement, The downside was the pricetag to build it, so with any decent mark-up over built costs, it just makes no sense. So now we are working on something else with similar improvements but much cheaper price tag.

I think B58 and N55 HPFPs are similar with just slightly different mounting. |

Alex tuned M340i. Good job! And I'm happy he is doing SAE not STD like others for bragging rights
Here is the comparison - 340i vs M340i (dyno charts from MP and seems done on the same dyno). Notice a decent advantage in stock form for M340i (which is expected), however I feel very comfortable for tuned version for ours F30 vehicles . I've scheduled my stg 3 dyno late August (dynojet) just out of curiosity, then hit the 1/4 mile strip. factory stock: 340i - 294/323 m340i - 338/381 tuned: 340i (stg2) 443/433 M340i (stg 1.5) 435/474

Yep, exactly right! Very with gains and drivability. This is faster than any stock F80 M3. Would be nice to line up with Tesla model 3 dual motor
Dyno coming late August then fall 1/4 mile

Another interesting observation, my gas mileage actually has been increased to 22.8mpg as an average with Shell 93. Obviously, I’m not running like nuts but not easy either.

I've been doing a lot of research trying to decide which flash tune to get and one of the main factors to me is the ability to retain linear throttle mapping (which is the default mapping for stock comfort and DSCoff modes). Can anyone or Alex himself comment on whether their tune retains the stock throttle maps for each mode? Or if it's possible to make every mode have a linear throttle map that'd be awesome as well. I just hate the feeling of that twitchy throttle in sport+. I remember MHD used to let you pick this as an option in their app back when I used them to flash my old N54, very convenient.

One of these days I'll find a used Draggy and a track that's cheap enough.

Hello guys...
I purchased my tune on the webpage but when I try to load it says vehicle not found... Tried to call MP... and their phone is disconnected... How long do I have to wait when I purchase it until I can load it? JC |

Also, vehicle not found error indicates that you have no connection between the laptop and your vehicle. Most likely causes are bad eNet cable, Ethernet adapter is not being set into automatic dhcp mode, or you having recently plugged in legacy (CAN) device to your OBD2 port. |
