BOOTMOD3 N55 Flash Tune
Graham Beckman
Sorted 435i

The Bootmod3 stage 1 tune sorted all the small issues coming from several small upgrades.
FTP charge, boost and inlet, Dinan cold air intake, 7.5" intercooler, DV+ diverter, JB+, VRSF hi flow downpipe and BMS catchcan.
Just done 3,000km this break and not a single error.

Great service

Purchased CSL intake and fitting kit from Andrew. Process was easy with fast delivery and came in the timeframe advised. Thanks Andrew for the great service👌

Easy and fast

Was no fuss, ordered, sent, here in a week like i needed

Must have upgrade

The VRSF 6.5” FMIC is an easy bolt on upgrade that offers great fitment & performance. Averaging 15C lower temps than the stock FMIC on a 20C day.

Noticeable power gains, would recommend even on a stock setup.

Great service!

Great product, in stock, hand delivered!


Works well easy to use

BM3 Stage1

I have just finished flashing stage 1 and I am supper pleased with the results.
Will play around with burbbles but happy that I went with stage 1 to start with, seeing I am 6 months of being 70 that proves just about anybody can do this.


Never received it

Hi Michael,
We're working with Protuningfreaks to establish why this isn't functioning as expected. Under normal circumstances these are applied automatically using you VIN. We requested this and unfortunately it appears yours didnt apply. This is a system that is out of our control. But please be aware we are doing our best to rectify with Protuningfreaks.

All I can say is WOW

2022 jcw hatch - fast nimble little car. We put the RS RaceChip in Chilli and totally blew my mind - we did a rough calculation that from 0-100 took approx 4 seconds. Mind you I have had people not believe this until they saw it. Totally recommend the RaceChip RS and the guys from Flashtuned. They are amazing.


Sounds awesome ! Totally worth the purchase and Andy was helpful every step of the way.

Totally satisfied. At 70+, from my teens I've owned many a quick car. The combined performance of the M135i and BM3 is totally beyond my experience.
Brilliant value for money.

Awaiting delivery of a usb to ethernet adapter. Will advise when I get a bit further.

Sounds great! Quick delivery

Awesome sounding intake, lots of turbo and intake noise, nothing to note power wise, maybe slight difference in response, but probably negligible. Can be combined with the hot climate mod on Fxx chassis for some direct air from the grill.

Great shopping experience with Flashtuned, sign up bonus was appreciated :)

Outstanding service

Andy was fantastic, very knowledgeable and came out to my house to do the work. Couldn’t be happier


Easy and simple install. Noticeable difference at stage 1 tune. I would recommend getting the downpipe and jump straight to stage 2 tune.

exceeded expectations

N55 F30 stage 1

BM3 stage 1 2013 F30 335i. I was prepared for an improvement but what I got was unbelievable. Car is a bit better to drive down low as well. Very Happy.

Sick tune

Andy was really helpful and love the tune

Cable for Bootmod3

Works faultlessly, handled a 2.75hr connection to the BootMod3 technicians without issue.

The Perfect Product

Not a noticeable difference in power, but hearing the turbo does change the feeling you get when driving. I have a few more upgrades on the way. I couldn't recommend Flashtuned any more then I can. Great people to buy from, a wealth of knowledge and excellent customer service.


Possibly the best mod you could ever do to a BMW. It really woke up my n20

MST R600 pod filter

Happy with product fits well not too long for delivery and reasonable price!

Cable does exactly what it's meant to do

Great product

Great tunes
