It’s flash, intercooler, turbo, and HPFP if you want more peak power consistently. If you want more peak power inconsistently, it’s a stage 2 flash and downpipe. If you want very little peak power increase but more power “under the curve,” inconsistently, it’s a flash only.

1. Do you know the stock turbo CFM? 2. What's the most popular turbo upgrade (not heavy hp, just a basic upgrade over stock). 3. What CFM does that turbo flow? I know the turbo, like the FR, is holding the tunes back, I just don't know what part, and studying flow maps isn't my thing. I'm looking for an answer like "stock turbo flows 400 CFM, and runs out of breath at 4800 rpm, and the most popular upgrade flows 550 CFM and corrects the high rpm hole and lengthens it." |

My whole thing is and I hope no one takes offense by it, as I'm a friendly, with two N55s; anything over 400hp, is tapping out the mechanical limits of this pump, i.e. motor. Regardless if it's the turbo, fuel or the actual motor, it's all the same to me, if you want more power, it's better to just upgrade vehicles, that pushing the powertrain to the edge, which it seems the stock M2 tune is already capping out at. |

So, in your opinion, it's best to... a.) upgrade the charge-pipe/intercooler/down-pipe/and use an OTS tune b.) upgrade everything listed above, but get a custom tune c.) upgrade everything listed above, plus a hybrid turbo/hpfpr/custom tune d.) leave it the hell alone. |

It's probably going to be ugly as sin but it's not going to lack, in the power department.. That's just my humble opinion.. |

My preference has always been aesthetics over ultimate performance, so I'll stick with the F87. The option for my car will be b.), as I much prefer custom tunes, and feel like BMW left a bit on the table that can be had for cheap without shortening the life of the engine a single minute. |

When condition is optimal, Dinan Piggyback can get close in performance, but it's way less consistent and also stress the fueling a lot more, boost for boost. Check out a few of my threads for more info.

My build is a little weird because my exhaust system is 100% stock, meaning the intake, downpipe, midpipe and axle back are all stock, but I do have an ER chargepipe. I only switched from their piggyback stage 4 to stage 1 flash because it was offered for free at my dealership - they are trying to move everyone to the flashes instead. |

Do you have an update/eta for the stage 2 flash for those with the stage 4 upgrades already? Excited to switch over. TIA |

That said, power wise its only a small step up from stage 1 as the biggest limiting factor is still fueling on the platform. |

Hi there,
Given the fugliness of the new M3/M4 I'm most likely buying out my M2 post lease and lightly modding it. If I were to install a quality intercooler (Wagner or similar) at the same time as the stage 1 93 flash would you still cover everything under your warranty? I'm assuming so but would like confirmation. I run 94 octane (PetroCan with Ethanol) only in the car. Thanks, Chris

EDIT: Speak of the devil. Unbeknownst to me apparently the sister facility in Utah had the opportunity to do the emissions stuff recently on an S2 M2 so this will actually be publicly released in the very near future. EDIT 2: Stage 2 released. Info can be found HERE. Last edited by Dinan_Engineering; 02-03-2021 at 03:11 PM.. Reason: Update again. |

I am not aware of doing any special programming/changes for a 6MT calibration. Of course its been quite some time since we have seen a N55 6MT M2 in house though as well. If there is something specific needed I am sure we could address it pretty quickly with a car exhibiting the issue in house to play with.

Dinantronics Stg 1 to Dinan Stg 2 Flash
Hi I am considering my options, I have a Dinantronics Stg 1 piggyback on my 2017 M2 6spd with the Dinan intercooler and HJS 300 cell sport cat...I am getting ready to add the Dinan Turbo.
Two questions, 1)given your exchange program what is the cost to go from the Dinantronics Stg 1 to the Flash Stg 2? 2) Does the flash adapt to get the benefit of the 300 cell sport cat? (if not is the power gained from the sport cat nullified or simply not fully realized?)
