Sorry if this a dumb question but why to stack with JB4 like M4HCP did? What can JB4 do additionally that the tune cannot? I was thinking of switching JB4 with bm3 as soon as it's out. But depending on the answer I may keep it as well.

Flashing with bootmod3 calibrates the engine computer the way factory intended. Everything form fueling, ignition timing, boost/load targets, valvetronic, exhaust flap settings, overrun (burble/sound tuning), cold start, various limits for torque levels, etc you name it are adjustable in the flash. Piggybacks don't have the ability to program the DME but they can influence the systems in realtime externally and play a convenience role as a secondary system for boost mapping, meth control, secondary port fuel injection control, etc for many. In our neck of the woods we like to call flashes front-end flashes and piggybacks backend controllers given where/what control is possible with each, not the other way around, but that nomenclature is up for debate LOL |

Importantly, this "dynamics" OTS map, would be ideal if it didn't increase peak boost pressure over OEM. Higher peak boost pressures take more time to reach and thus increase turbo lag. So, although many people would hate this, a map with lower peak boost that maintains near-stock HP (via ECU timings or whatever) would be worthwhile IMO. I'm not sure if that is technically feasible though. |

Have you guys been able to achieve something similar to this (991.2, also a 3.0L twin-turbo): This appears to be the holy grail of FI-engine linearity. It's effin beautiful. |

proTUNING Freaks For those with JB4 currently is there an advantage or disadvantage of using it of a stack ?
Currently the advantage is the boost control of course and map switching on the fly via bluetooth. But there's also some disadvantage where was the JB4 needs more Boost when run as Backend than say a Full Flash tune car to put out the same power.

My take on the JB is this. You get yourself the most power you can with a flash only and then see where you sit. At that point see what you get with a JB on top if you like maybe to run low boost but at the same time map switch is like a minute or so. Why switch maps though unless your mods or octane changes just makes no sense.

What boost you 'can' run is a function of octane and hardware on the car. Boost though is just one part of the equation. You have to ensure ignition timing and fuel are on appropriately set for a given boost profile that ensures the most power without significant knock (i.e. reliable power that keeps your car out of the shop and away from potentially very expensive repairs). One disadvantage might be, not sure you can call it that really, is you need to be in map 0 on the JB4 (or any piggyback using the diagnostic bus in the car) to use bootmod3's diagnostic and logging features. These features are something we're working on expanding constantly and there are plans there for quite a bit more than datalogging and the live dash that we already have in beta. |

Not sure where in Europe you are but we've received quite a bit of feedback from shops in Europe in regards to bootmod3. Halim who's part of PTF is in Denmark. You should be set.
