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.

BMW M5 Tuning at Llandow Tuning
No Off the Shelf Map

We evulated the engine tuning on this car, made a few modifications but didn't recommending redoing the whole thing as it wasn't bad.
Gearbox tuning, and a VMAX and a fix to the Cat Off solution that had been applied.

I did think that the MAF setup in those silicon pipes were silly. Seen it quite a few times before. It means the value from the MAF cannot be trusted as it changes as the pipe deforms as the engine sucks air. Should be a solid housing. But they make a nice noise. Don't think they make any difference to the power output really.

BMW 116D B37

Stage1 Plus Calibration done on the dyno like everything we do at Llandow Tuning. A completely custom calibration tweaked to the car to get the most out of it within safe limits. Not some off the shelf junk or something from some automated program.

The dyno isn't really about getting a HP number, it is about proving the calibration is safe via data logging.

I don't think you'll find another tuning center in Wales that noy only does everything on the dyno, but data logs and has never been a reseller for another tuner or used slave tools.
