Daily driver with ~64k miles. It’s a 2015 bmw 535ix. Currently installed is a K&N intake and an Eisenmann performance quad race exhaust.

I want a CPO M550 (yes the V8...), but a Kbb trade in value of my car at $19k is insulting. Figure I would mod and enjoy it a few more years.

Bootmod 535 Flash tune + Free Enet Cable + All Maps
VRSF F Chassis 535 Race Intercooler
VRSF F10 535 Charge Pipe
VRSF F10 535 Downpipe Catless 4"

All of the above completely necessary? Expected hp gains? Catless versus catted Downpipe? It is my daily driver.

If your 2015 EWG than its worth it. Basically from what I heard you can get Pure Stage 1 type of power out of it with those mods. I would also get the o2 spacer than you can pass emissions.

[Mmoon024]

Yes 2015 EWG. Thank you for the tip, definitely want to be able to pass emissions.

Just keep in mind that you might have to enable catalytic converter check. I dont know how that works in bootmod3. I have MHD and by default catalytic converter check was disabled so I failed my emissions, but than once I enabled that I was able to pass without any issues.

I don't know how bootmod3 compares to MHP, and what gains are for bootmod3. MHP publishes their numbers for F10 N55 at https://mhdtuning.com/mhd-flasher-f-series-n55/ so with MHP you could get with upgraded intercooler, chargepipe and high flow downpipe 430HP and 480 lb ft of torque
You may want to consider high flow downpipe with "race" cats instead of catless downpipe

MHP would be around $450 which includes monitoring module ($200 less than bootmod3).
If you want to save more money, you can consider G-Plus intercooler which seems to be replica of Wagener intercooler but in $250 range and it has received very good reviews, see https://f10.5post.com/forums/showthread.php?t=1585080

All very good points up top but I would still do catless dp.

And of course it is MHD and not MHP lol.

[dzz]

yes, MHD, I got it confused with XHP transmission tune https://www.xhpflashtool.com/ that I also have along with MHD and I highly recommend this combo

[$howtime456]

looking at around 420hp when its all said and done. Your turbo is holding you back as well as custome tune. Add sprint booster , inlet and , xdi hpfp , and xhp transmission flash if your serious about making power

I would say xhp for sure as that will help maintain correct line pressure for the torque. Best bet is go g-plus intercooler + mhd and use the save money to get xhp tune.

I second this. VRSF intercooler hardware is hit or miss (Tiago will claim otherwise, but I've still yet to receive the correct brackets, despite contacting him as he requested + tons of back and forth about it via PM; start at post #71 https://f10.5post.com/forums/showthread.php?t=1564333 )

Go for the G-Plus intercooler or Wagner + MHD (or maybe the JB4/MHD stack) + xHP tune.

I just bought 2010 e92 335i and ordered my self g-plus intercooler and the built quality on that thing is better than VRSF which I have in my F10.

Add sprint booster even with flash tune? (bm3)

Met with an installer he said with the intercooler, downpipes and chargepipe I was looking at 14 hours of labor. Seemed excessive. He also said a carbon cleaning was necessary prior to any tuning. Its a 2015 535ix n55 with routine maintenance performed. Currently ~64k miles.

MHD looks solid but does seem to support iOS or MacOS which I don't have android device.

[dzz]

you have same car as mine, 14 hours without carbon cleaning seems very excessive. I have chargepipe already installed and I am interested doing other mods like you, I am going to ask my shop tomorrow how many hours all 3 would take to install

[Mmoon024]

Looking a new shop myself and having a hard time finding an installer.

Lawl 14 hours? All that work can be done in literally 3 hours. The only pain is downpipes that can take up to 2 hours. So to keep it safe bet it should all be done in 5 hours max.

Flash tune is good but the sprint booster eliminated all the throttle lag for me!! Tuned with the sprint booster .

I have wagner and A+ in my books.

What brand chargepipe did you go with? I was looking at switching my VRSF to Evolution Racewerks.

[Mmoon024]

1)VRSF RACE INTERCOOLER FMIC 09 -16 BMW 535I
2)EVOLUTION RACEWERKS F CHASSIS N55 535 / 640 CHARGE PIPE
3)EVOLUTION RACEWERKS N55 535 640 LOWER INTERCOOLER CHARGE PIPE (LIC)
4)ER COMPETITION SERIES 4" CATLESS DOWNPIPE (F10/F12/F13 N55 ENGINE)
Additional O2 sensor:Yes +20$. EGT bung:Yes +15$.
5)BOOTMOD3 FLASH TUNE


Considering switching out VRSF for ER. Better quality? Also added lower intercooler chargepipe, worth it?

I was in my local indy shop and I've asked:

Chargepipe about 1hr
Downpipe about 2hrs
Intercooler 2-2.5hrs depending on the fitment and if any trimming is needed

Worst case 5.5 hrs total and even if you round it up to 6 hours, it looks like that a person you went to, wanted to do your work and then take a paid day off for a total of 14hrs :-)

[Mmoon024]

Found a local tuning shop that happens to be an Evolution Racewerks dealer. Quoted me $380 to install everything. Just took finding someone that knows what they're doing and wants repeat business! I’ll post numbers in the coming weeks once everything is put together.
