Hi all - I'm looking to get my N20 engine remapped and have had these guys suggested.
Has anyone any experience with them ?

I’ve not used them / heard of them..but..

Their out of date website (2012) and Facebook (2016). doesn’t fill me with contemporary confidence….

There are other suppliers available….

Agree with the above. N20 re-mapping is so common that every man and his dog is doing it. If you look at claimed figures, they will all be very similar, as they all use the underlying same map. Unless it's a bespoke map done in real time on a dyno to your specific engine's characteristics, but marketing plays a part, so they all claim to be the highest output.
If they are claiming 280 ish bhp and 350ish NM torque, they will be the same map. Pay your money, take your choice.

Whoever you choose just make sure its on a dyno so you have some representation of any gains as opposed to writing on a box/app or promises..

A bit late to this thread but...
I had my N20 done at dc remapping in Warrington 18 months ago. Car is running great and not had any issues.

Have you got a dyno chart you could post?

Hi... Usual time delayed response from me... This is the dyno-chart from DC.

Thanks, looks like a pretty typical N20 engine and associated tune.

What model year is your car?

It's a 2013.
Still going strong as well.

Guys, what can you say about my dyno results?

Original HP is way lower than your results, (some says it might be about the octane levels.)

It comes back to life after remap, same 260’s.
But torque is a bit higher than all stg1 remaps I have seen. (Which is also the gear tq limit.) Do you think it should be lowered?

What model year was your car and type?

Looks like a 18i as a base line…

Often tuners tweak / end up with more mid range torque at the expense of ultimate hp..not a bad thing for road use, especially with the auto box..

It is a 2014 model, m sports, 2.0i, which should be 184hp.

All of the 4 cylinder turbo cars are 2.0, either 18i, 20i or 28i varieties - it’s strange the tested power was the 18i level?
