Mike mentioned that 4psi boost will give 93AKI a kick, as I'm sure it would for 98RON as well. Mike, can you please explain what each parameter adjusts? Thanks

Pulse Width Modulation, I believed that would control the duty cycle for the wastegate solenoid.

So an extra psi, which is worth maybe 10hp or so tops. Might be worth doing only if it's confirmed first, 4psi on 93 and maybe 3psi is for 91-92.

I would check with BMS but the default is 3psi, I would think any more then that is not advisable without higher grade octane than 91. I put in 93 now on the default setting. I just want to know if I can bump up the extra psi.

Ok, so I raise the boost to 4psi for 93, what about the PWM you circled-do I change that number?

Now to consider the USB cable or maybe wait for stage 2 and buy both (unless the USB comes with S2). Exciting times ahead.

Yeah, I am figuring I will need the cable either way.

Mike, is the stock stock turbo capable of pushing past 23psi efficiently?

Also remember its not necessarily peak boost but the full boost curve, and efficiencies will vary by RPM and mods. I can tell you stage2 is being pushed to around 23PSI +/- Mike |

Alright! finally got the tune, installed today and took it for a test run...
Overall, the beast is finally out of its cage. The car feels like its been opened, you feel that extra hidden power in the car which it didn't have before the tune. Personally totally worth it! My car feels fassssssssttt To be honest, it doesn't feel like its incredibly fast as BMS stated "4.9 secs" But I will admit, it feels pretty close!!!! Which is amazing! but not like you are driving a 4.9 second car. But i am sure with stage 2 it will either reach to that level or might even surpass it. I cannot wait for stage 2!!! I highly recommend the tune! You will love it soo much you wouldn't want to get out of your car! BTW ima do 0-60 times either tonight or tomorrow! Most likely tonight! hopefully! |

Got ya! Ya, I wouldn't want to trust raising the boost if im running 91. If i was running a higher octane fuel, most definitely will. But hey! Its enjoyable regardless without the boost raise! freaking fast enough my man! Stage 2 here i come!

In addition, they would have used 94AKI (98RON) gas. Being conservative, we probably have 5.1 - 5.4 sec 0-60mph / 5.3 - 5.6 sec 0-100kmh cars @ 3psi boost, possibly faster.

Sounds great. Looking forward to it. Don't forget to warm the engine up fully before the hard run. Cheers

Oh I won't forget, ima make sure it's properly warmed up before i hit the road and do a 0-60 run. I have a feeling it will be from 0-60 in 5.5 - 5.4 seconds. Well i mean as you stated |

When I took delivery of my F30, the dealer put a tankful of 95RON and almost immediately after I started driving with the first fresh tankful of 98RON, I could feel a performance improvement. So, yes, if I was to boost the turbo to 4psi, I would certainly expect to feel an improvement with the 98RON. I need the USB cable first.
