The Audi RS3 has been at the forefront of the hot hatch arms race ever since the original made its grand entrance in 2011. The second generation stuck to the same mechanical template of the muscular turbocharged five-cylinder engine up front, sending its power to all four wheels.

The stunning Audi RS3 not only looks the part but it also pulls 367bhp in standard form. And for most people this would be more than enough power in the 4wd car. But as we find with most of our customers more power is always needed 😉

Slowly parts where bought and changed on the car. Induction kit, secondary decat pipes, decat pipes and front mount intercooler where fitted and the car was mapped to suit along the way.

The Audi RS3 ran a 11.92 at 113mph down at Ultimate Street Car in 2017.

So where do you go next after you have modified the car like above?

Hybrid turbo! 😆

A second turbo was sent over to our “Turbo Guru” for hybridizing. With a bigger, modified compressor wheel fitted and the rest of the internals upgraded it was time to fit the hybrid turbo.

Original ‘V’ Hybrid

With the hybrid turbo fitted, the Audi RS3 had the Haldex 4wd system disabled and the car was strapped down to the rolling road.

The Mapping Process Began…

As we had put a lot of time and development into the Audi RS3 over the last couple of years. Mapping it to suit the next modification and working closely with the “Turbo Guru” and the owner we knew what we needed to get out of the car.

Our aim was to create a remap to suit the car that will not only deliver the power like it would out of the factory but be reliable in its delivery.

Here is what the beast of a car made on the rolling road…

So ADE Tuning increased the power and performance of this stunning Audi RS3.


This car is a one off build and the car started out life as a mk1 Golf. The build consisted of putting the mk1 body on to a Audi TT chassis. But this wasn’t a simple build. Jems Speed Shop enlisted the fabricating experts Jo’s fab lab to build the car. Jo’s fab lab made the body kit out of steel and rolled and folded metal making the car bespoke in every way. The car was 8 inch wider than the Audi TT base so the car was split in two and widened to fit. The car has the 225bhp engine and that combined with the Audi four wheel drive system makes this car a dream to drive.

So the car went up for sale and the new owner brought the car down to ADE Tuning to find out about an ECU remap.

This is where we get to work our magic 😉

An Audi TT has the Haldex 4wd system. So we disengaged it before we strapped it down on to the rolling road. As with all our ecu remaps we ran the car for a health check and to find what power we where working with. The car pulled 200bhp which was expected as this is the general power figure we see in the MK1 TT’s. The custom remap was written and the car was run on the rolling road throughout. Once we where happy with the cars ecu remap gains we re-engaged the haldex and went on a road test.

The car performed effortless with the throttle response greatly improved and the mid-range drive spot on, not to mention the increase in power.

The Audi TT/ Mk1 VW Golf will be heading down to Ultimate Dubs in a few weeks so be sure to check it out, not that you can miss it 😉
