BMW N47 Minus Oil Changes!

Whilst we still seem to fix a lot of N47 engines, mainly DPF related now, this one has the worst oil filter we've seen this year.

Oil Flush done, but how good the engine is now, who knows?

Sometimes we even have to flash the ECU whilst its still on the car...

Whatever ECU or car you have, we've been tuning vehicles since 2004 and everything we do is done on the dyno and tested, not just given a quick test drive.

Think your turbo is under boosting?

We've been offering smoke probes for so long, that when we started offering it you couldn't even get a smoke probe in the UK and we had to import it directly from the states.

Don't forget we offer a free assessment and code scan weekdays after 10AM.

BMW G20 Unlocked and Dyno Tuned
No Off the shelf one size fits all calibration

Yes we've seen the claims from other of "dyno proven" and "live map" but unless it goes on the dyno it is little more than snake oil

If you've got a vehicle that you want dyno tested and a custom calibration created, drop us a message.

Whether a stock vehicle, one with a few simple mods or even something with some massive turbo. We're happy to help

Don't forget our current tuning discount will soon be ending!

BMW 135i for some live power runs.
What did we find? The off the shelf map claiming 400+HP made around 370HP

The moral of the story is as always, if someone says dyno proven, they mean its an off the shelf file taking from someone elses cars applied to your car and untested.
A quick code scan is not the same as data logging on the dyno. Even with data logging on the road, you cannot on the road maintain a steady RPM and load the vehicle up.

Really Big Flames and the loudest Pops we've ever done. To the point we've all lost our hearing!

The customer said loud, its very loud and over 430HP thus far. Some more tweaks to do and the car will be ready to go home

No we don't do off the shelf tuning. And sometimes it takes a little while to get really custom builds bang on!

Yes we can do stage 1 and 2 quite quickly

But if you want different injectors or different turbo running right, we like to get it right too. We don't rush, we don't guess, we run the car as many times as needed, collect data and tweak the map.

This is a race/track car and thus for non road use. I would highly recommend anyone thinking about using a car with pops on the road understand the legalities

Further to this, the customer didn't request it. But I mad the pops switchable. Why? Well I am sure even on the track not every run needs to have anti lag pops.
And should the chap run it on the road, it can be run in a way which wont fall foul of legislation making pops and bangs illegal.
If the chap wants to sit in a field or on private land shooting flames out the back, I am yet to see what law that would be breaking and I say more power to him, its his car and we don't yet live in a totalitarian state.

As for my opinion on pops. I think driving down a high street making yourself look like a tit with the car popping doesn't do the car scene any favors and it gives am******on to car haters and frankly a certain type of person that we all know.
But by the same token I object to loud music from cars when sitting outside a pub and having to breeth in smoke from smokers/vapers. Yet somehow that's allowed.
