So, the dynos presented were a 20 pct reduction in all gears? It was run in 5th gear for the dyno to " show" how it works, but we wouldn't actually reduce it in 5th gear for the street, correct?? Just a reduction in 1-3 for traction but having the higher top end rush in the higher gears of a custom tune over OEM?

Based on what you just stated, it sounds like the stage 2 map is the better choice since now you can "shape" hp and torque curves in the gears you wish and still arrive at higher torque and HP " when you want". Pretty cool if so.

It's lowered in torque by percentage |

given there is like 12% reduction in actual max torque from the dyno (from 578 lb-ft to 508 lb-ft) when it's set as 20% reduction, then it's more like to set it as 15% reduction for Stage 1 91 OCT (given lower max torque output at ~545 lb-ft)? of course one will need to test it on dyno to confirm the right setting.

Well thing is, the maximum torque allowed torque is not reached so going 20% will reduce that maximum allowed torque by 20% But you will see a dramatic change going from 10% to 20% to 30% (you will be doing less than factory TQ here).

Great explanations and great feature!
If I understand all this correctly, this feature should maybe have a different name? Now it's "Boost By Gear (% Reduction)" - which one would assume means that, well, the boost is reduced by the percentage you enter. But what you're saying is what is really happening is that the torque limit of your current map is reduced by the percentage you enter, which is something pretty different. So should it be called Torque Limit By Gear (% Reduction) instead? And would it be possible to maybe actually show the default torque limit on that page? Or display it somewhere at least? That would make it easier to understand the expected outcome.

Novice tuning question, to revive this thread.
I’m running now the Stage 1 93 oct, east coast. I was running BM3 CS map before. I love the Stage 1, but it was suggested since I track my car, to run a torque limitation on the Stage 1 map, for crank hub failure prevention. Given the expertise on this thread, what torque limitation settings do you recommend? 10% or 15%? As a reminder I am running 93 octane, and I’ve never felt traction-limited since I never do launches. Needless to say, on track with 305 NT01 rears, no problem with traction. The thought goes more towards avoiding potential spunk crank hub failures... Any advice would be very appreciated!

@adc - little late to the party - but this might be helpful.
I've been doing a number of trackdays in my car, and here's how I've set it. Mods are Stage 2 91 map, Advan a050's, BBK, catless downpipes and CBC. I run 93 ron (aussie 98), so went a more conservative tune). Longest sessions are about ~20 mins, this seems to have worked well. Cheers, matt |

I’ve run the following reduction settings over the last 2 track events (and daily driving): 20, 10, 10, 0, 0, 0. I am probably making less power than you are, but I’ll try your settings at the next event in the spring. Cheers!

I still find this to be a fascinating subject
Halim@HCP when I compare the M3 PureTurbos torque limited map to the M4 stock turbos torque limited map, is it just me or are they pretty much identical? I would have expected larger turbos that are torque limited to produce a lot of top end, certainly more than the stock turbos. I have no interest in tons of midrange torque, but would like more power up top. Before seeing these results one might think that a torque limited pureturbo setup is the ultimate for me.
