Bm3 vs custom tune
So I did the FMIC, DP, and CP all in one go and then bumped my dinan sport tuner from sport+ to race, i believe in race its doing +4psi. It certainly feels a bit ballsy-er. I really should have tried out the car with the dinan in sport+ first to see if i really felt a difference but oh well
So now Im debating on how to get my stage two 93 octane tune. I don't know if I should get an OTS tune from BM3 or get a custom tune from DME tuners here in northern jersey. Its ~600 one way or ~1700 the other. Is a custom tune much better than a OTS tune? What's the real differences? Another concern I have is if something goes wrong with an OTS I'm not sure how car savvy I am to figure it out. 1700 is a lot more that 500 but that seems like pay the professionals and be done with it could be worth it. Idk I'm torn, what are your opinions guys? heres their website: http://dmetuning.com/ |

9/10 times you will not be able to tell the difference with a custom tune. A custom tune is more if you do ethanol blends, have bigger turbo, are running methanol injection etc. I would save the money if I were you with those basic bolt-ons.

And it could take months or years. Maps are thrown out of window one update after another, still looking at OTS wondering if should start it all over again

It's not always a question of squeezing more performance but also adjust to the car specifics, e.g if you're unlucky to have a weak HP fuel pump, you can run a tune that is better adjusted
However in EU a custom tune is more around 600 than 1700 as you mention, surely you can get a custom tune around those prices too in US?

Also, the person who quoted you $1700 for a custom tune is crazy expensive! I have several tuners at my disposal here in AZ that will put together a custom tune (non BM3 related of course) for well under $1k. |

I would have agreed with this post until yesterday.
I was at a shop where a well known maxed out “super” F30 on this forum was on a dyno. Remind you, this PWG F30 has BM3 tuned by several who specialize in custom tuning, Pure S2, Full E85 and all the other goodies. You would know the car if I revealed the forum handle. It only pulled about 420HP/413 Torque. This car is claimed to do over 500HP and Torque on forum. You would also know the “nicks” of the tuners who claimed to have “dialed in” this car on the forum. Then a “stock” PWG F30 with only an aftermarket Downpipe and a custom tune (not BM3 or MHD etc) was put on dyno where it did over 457 Torque. BTW, this car was an XDrive The place the dyno was run had no skin in the game and to them it was just 2 F30 of the same year with no idea what was under the hood. After being there for everything, I will tell you that my eyes were truly opened and I learned yet again (well even more than before) not to believe all the posters with supposed “facts” as well as claims of the tunes on the forum, no matter the size of their following. If I had the choice, I would have gladly paid $1700+ for that tune instead of $10k+ of equipment plus the $595 BM3 of the “super” F30. PS I will be the first to admit the “super” F30 did hold better at higher RPM with the Pure S2 and E85 able to supply fuel at higher RPM, but still.... Now, the interesting story will be what the same tuner can do to the “Super” F30 once BM3 is removed. Last edited by IK6SPEED; 08-11-2018 at 12:43 AM.. |

I'm just waiting to get the tune and PI all set up properly. I made 456/438 at the wheels with JB4, meth (50/50 boost juice), and like 23psi of boost. I'm hoping I made the right call in ditching all that and going for and ECU tune.
