@kfer I went back and looked at some my BM3 logs from stage 1, 2, now custom. BM3 or the tuners using it look to be scaling variables to trick the factory management system. I would do similar on some of my older boosted v8s that were not designed to see loads/VE much over 100%. Could this be...

The more power I make the less pops and bangs I want. Currently have all burbles turned off or minimized for a more sleeper experience.

The OP stated that he is working with the Titan/Snow system. I have that system too. It came with two nozzles. To differentiate, as the look identical, there is a number stamped on them. Maybe I'm wrong, educate me.

What nozzle size and how many? The 4 is 250 ml/min and 6 is 375 ml/min I think. Full meth or 50/50? So many questions, how are you determining the delay, IAT fuel trim?

Here is more fuel for the 40 weight fire. "For daily use 0/5W30 oils are excellent choice. I use XW40 just because I track car." https://bobistheoilguy.com/forums/threads/castrol-edge-0w30-has-bmw-ll01-again.363833/page-5#post-6475520 Here we have mention that high HTHS may slow spool. To me...

I got notification mine shipped today, or at least a shipping label created... I have been waiting a couple weeks for those parts to arrive to BM3.

@kfer the MAF is supposed to do that (max out). Apparently BMW engine management strategy does not use MAF for high flow/load conditions.

Installed eibach front sway bar. It was super easy and on softest setting makes a difference. The rear sway bar looks much harder to install, maybe this weekend. Any tips for the rear sway bar install?

Let's try to understand what this dude @Eddyvw is throwing down, because it's profound. "Take into consideration that when you say "grade" that is KV at 100c. Your BMW in regular driving is running around 109-113c. That means that at regular driving, your oil is bit thinner than you think. That...

I would do some reading on a thread like this: https://bobistheoilguy.com/forums/threads/bmw-b58-engine-oil-recommendation.337089/ Meeting certain BMW oil specifications (LL01 LL04 LL17FE) are more important than just oil weight. Higher HTHS values are important for protection. If you run...

I am not a chemical engineer although I am an engineer. Therefore I am no expert, I just read some stuff on an oil website many years ago and have applied it to my high performance engines over the years. Approvals matter in the BMW B58 world, make sure you choose a LL01 or LL04 approved or...

It looks like a pretty standard BM3 tune, other than the timing corrections being larger than normal. It calls for 21.x psi of boost and makes almost that, WG is working for boost control, lambda is pretty normal 0.84-0.82, actual and command lambda follow well, fuel trim is slightly further...

Oh wow, those codes makes you think the wastegate or actuator is getting stuck. Maybe have a peek at the WG actuator and linkage to make sure all looks ok.

For what it's worth, I purchased a CTS turbo and let it sit around for months without installing. I figured without more octane it would not be much better than BM3 stage 2 ots with stock turbo and water meth. I was wrong, the CTS is awesome and I can't believe the difference in power with the...

If I was rarely getting into boost and doing lots of short trips a spec meeting 0w-20 is probably fine. I run 5w-30 penzoil euro if its cold and wet, meaning very little boost. I run 5w-40 if its warm and dry. It hurts my head to think of 20-30 pounds of boost, summer weather, sustained boost...

Close to 500 whp seems pretty possible with the results people have been getting from Pure, CTS, etc stock location hybrid turbos on 91 octane. Plus stock location turbos look stock.

I have 20K miles on a 2020 supra and recently installed a CTS turbo. The stock turbo has no perceivable shaft play. Granted I did not run the factory suggested oil for very long, before moving to a more appropriate oil. Edit: BM3 stage 2 was run for 17K miles.

I reside in a State that has little to no E85, which is a fairly new experience for me. I remember times before E85 was a thing and we had to use order methanol and C16 race gas. What do the unfortunate souls that don't have E85 at the pump do for octane in these cars? I have started by...
