And a flash tune is better than a piggyback in every way. You're reprogramming the actual ECU rather than splicing into the ECU and overriding what it's telling the car to do. It makes for a much smoother and linear/usable powerband and driving experience. No there is a definite benefit to adding a downpipe. A catless or high-flow catted downpipe is a lot less restrictive which increases hp/tq. Almost all of the flash tunes recommend a better downpipe for anything past a Stage 1 flash because of the better exhaust flow for the higher psi the turbo will be pushing. |

You can probably get away without a DP (for a short time) on a Stage 2 or greater, JB4, etc., but the life of your turbo will likely be reduced long-term. A DP is needed to reduce the amount of heat you are producing from added boost, timing, etc. |

So the supra and at least my buddy's G05 X5 is b58tu, we tried flashing it last night but it wasn't supported. After checking with support, dzenan told us the tables aren't the same as b58 and they will need some time to have full support added but it should be out soon.

I took a datalog after a fresh flash. Not sure how to submit it to PTF to make sure everything looks okay so posting it here:
https://datazap.me/u/jrdoming/bm3-st...15-16-17-18-29 Edit: Can someone recommend the most aggressive burble setting I can safely do on Stage 1 with a stock DP? Last edited by jrdoming; 04-04-2019 at 09:45 AM.. |

And yeah I saw a thread about it but didn't expect it to change. When I received my car in 09/2017 it came with that software change so I never missed it and honestly got used to it. I kind of freaked out when I downshifted to 2nd in my neighborhood and the rpms jumped haha. Quote:

In reality the downpipe itself doesn't improve power, but it allows you to run a more aggressive tune safely. If the tune can't run more aggressively, safely, then there's no benefit in swapping the hardware. Hope that makes sense. |

Flash went through from every indication and car *feels* faster. I am not at high elevation but this could be a case of it not fully adapting yet. The log was nearly directly after a fresh flash so I might have to drive around a bit more to let this adapt up?

Maybe drive around and then take another log? Try 93 instead of 91 octane too.

Definitely could be the case of not fully adapting yet. I flashed 91 last night also and I've noticed a substantial difference even with just Stage 1

A lot of people are reporting not hitting boost targets. I specifically didn't comment on power because I didn't feel a huge change with 93 Stage 1, but I also expect it to take some time to adapt. I'd rather the car incrementally adjust itself up to peak power and make sure it's able to compensate vs throwing everything at it on the first pull. It's the right way to do things.
Hopefully this weekend I'll find time run logs to make sure everything is ok after getting some miles on the car. |

What 'adaptation'? I'd love to hear from PTF or another tuner if there is actual adaptation going on post-flash, but I haven't seen any actual info on any. |

Been reading their faq/docs...
There's a map editor built in, but can you edit OTS maps, or can you only edit starting from stock? Basically, could I get the OTS map, and just flatten the throttle mapping myself? Edit: Answered my own question.. in the manual: "Importing and editing bootmod3’s OTS maps is not an option. " |
