Sunday morning drive on the Chennai highway with a Stage 2 M340i .
Clean roads, pure boost, and that unreal exhaust note.

A few months ago, we came across a Reel by @b.choww that really MOVED US.
It was the story of a die-hard bike and car enthusiast whose life changed in an instant. A devastating road accident left him paralysed from the waist down 😢
For many, that would’ve been the end of the road. But @nakul.shetty2 with his never give-up motto has gone onto INSPIRE MILLIONS.
When we finally met him, we understood why he’s one of the most INSPIRATIONAL HUMAN BEINGS we’ve met.
Just grit, resilience, and an unshakable love for machines who refused to let circumstances decide his limits.
He got a custom driving setup done on his i20 N-Line borrowing ideas from race cars driven by Paraplegic professional drivers.
He took control again, and proved that passion doesn’t need permission.
Deeply moved by this story, we sponsored Nakul a Stage 1 ECU Tune, so every throttle input, every kilometre, and every drive reminds him of one thing — Your PASSION is stronger than your setbacks.
Keep inspiring, Nakul. The roads are yours to conquer 🏁
The PLATFORM that started it all for Harmonixx Tuning back in 2017.
Over 200 vRS' tuned, which is probably more than all other Tuning Shops in India combined.
Here is one of our favourite builds of all time.
A COMPLETE Package.
Hybrid Turbo, Cooling & Fuelling Mods, Exhaust, Intake, Suspension, Brakes, Tyres & Alloys, subtle Aesthetic mods too.
Builds that are CHERISHED by the owners, envied & copied by the rest.
People know us for our BMW builds in the last few years, but we haven't forgotten our roots.
Hopefully 2026 is the year we may get to showcase our Magic on the newly launched Golf GTI MK8.5 and Skoda Octavia RS Mk4.
Harmonixx Tuning - Home to some of the FASTEST and most RELIABLE MQB Builds in India.

They said it couldn’t be done. Not on a tiny Hybrid Turbo and definitely not on a Stock Block & Stock Gearbox.
This is our shop BMW M340i with the Pure800 FBO Setup.
This car ran a 10.2s 1/4 Mile consistently in Round 1 and Round 2 of the INDRC in the beginning of 2025.
Our client @karthikkv01 piloted this car and WON Round 1 and Round 2 of INDRC and most people couldn’t believe this was done on a Pure800 setup.
This time we made a few simple changes and tried to improve upon the timings from the previous round.
And behold, over the weekend both our drivers clocked consistent 10.0x runs all weekend.
In the process, @karthikkv01 WON Round 4 & Round 5 of the INDRC 2025 and @rahulrkodidini came 1st in Round 3 and 2nd in Round 4 and Round 5.
Unfortunately, we only realised on Friday night when we looked at the Datalogs that the TCU Tune was short-shifting every gear at around 6300-6400 RPM. We tried several custom settings but nothing worked and @xhpflashtool was already closed for the weekend, so they could fix this on time for that elusive 9s Run.
Very soon this car is going to hit 9s in 1/4 Mile once we fix the TCU Tune.
We end the year with WINNING all 5 Rounds of INDRC with this build and both our M340i drivers are #1 and #2 in the Championship.
All on a TINY Hybrid Turbo + STOCK Engine + STOCK Gearbox & even STOCK Suspension!
A huge shout out to all our part suppliers @pureturbos.eu , @pureturbos , @activeautowerke , @do88performance , @csf_radiators , @motiv_motorsport , @injectordynamics and others.
All this wouldn't have been possible without the @femtoevo unlock, @protuningfreaks and @xhpflashtool .
And a biggest shout out to @kagantuned for patiently dialing in the tune, not only to do such incredible times but at the same time maintain stock like reliability as well.
This car is still a daily driver and during long journeys it also returns 14kmpl on the same tune.
Over and Out....
What does a catback do on the BMW M340i LCI/LCI2 variants?
So the LCI1/LCI2 cars come with HIGHLY RESTRICTIVE Catalytic Convertors and OPFs in the Mid-Pipes.
This is where ALL the RESTRICTION is. So changing just the catback doesn’t really make a huge difference to be honest.
Now listen for yourself and let us know what you think in the comments below.
Worth it or not worth it?
Why doing PREVENTIVE MAINTENANCE & COMMUNICATING with your TUNER is very important for our cars.
And please don’t go around doing mods listening to some guy on YouTube who says, do this or that to get cool BOV sounds and ruin your cars.
This so called mod was making the car RUN LEAN and that along with the clogged filter kept throwing issues on this Hyundai i20 N-Line.
This customer has been getting CELs for over 2 months randomly & he never mentioned to us that he had done this “mod”. And we kept wondering how a tune that has worked on so many cars, keeps throwing CEL on this car alone.
After spend hours on the Dyno assuming it was a tune issue that needed fix, we popped the hood up and there it was, staring at us like a sore thumb in the engine bay.
Put it back to stock configuration and the Lean Codes went away immediately!
The car wasn’t making the rated power yet, and turns out the Air Filter hadn’t been cleaned in ages. Once we fixed that, the car made rated power like the 100s of i20s we’ve tuned over the years.
If you do any mod on the car, please INFORM your tuner so they are aware of what you've done. And please change oil on time, clean your air filters and change spark plugs from time to time.

Saving Porsche’s in India, ONE car at a time.
In the last couple of years, we’ve worked on dozens of Porsches that came to us with issues no one could diagnose or fix.
And we’ve realised something — the “ART of DIAGNOSIS” is almost EXTINCT in most workshops/dealerships today.
Everyone wants to swap parts and pray the issue disappears… But that’s not how we do it at Harmonixx.
This Porsche Cayman 981 3.4L NA came in with a CEL (Check Engine Light), the car was barely moving as the CEL had triggered LIMP-HOME Mode.
We scanned the car, traced and found the real culprit — rats munching through wiring & the change-over-valve in a spot that’s not easy to get to.
Our Team repaired everything in under 5 hours. We then Dyno’d the car to make sure it was running fine and it made 319HP and 352Nm (Porsche claims 320HP and 370Nm).
The same evening we delivered the car, and here’s the best part:
The owner drove from Bangalore → Coorg over the weekend and when we reached out to him, he said “Car drives SMOOTH with NO PROBLEMS”.
He had stopped driving the car for several months thanks to the issues that plagued the car.
That’s diagnosis. That’s craftsmanship. That’s Harmonixx.
Do you have a Porsche that needs fixing?
