[Fast boy]

Had a look around the site and there are not many up to date posts for UK tuning.

I have a 2015 crdi 108 Hp which I am looking to tune was thinking of using Quantum tuning but could be persuaded to go elsewhere.

Based in Edinburgh Scotland.

Any views welcome.

Thanks in advance.

Welcome.  There was quite a bit of torque talk about tuning boxes and ecu mapping with the original series 1 (FD) model, but as you say not so much with the series 2 (GD) for some reason.

They are essentially the same motor.

There is also RaceChip, they're well known and give good results Chip tuning Hyundai i30 (GD) 1.6 CRDi | From Racechip

Choose the far right drop down for your vehicle power trim.

Fast boy do you want an actual ECU remap or just a tuning chip, i.e. magic black box?

Also you might want to have a look into this: TDI-Tuning - Hyundai i30 1.6 CRDi Blue Drive 108 BHP / 110 PS / 81 KW / 260 NM / 192 LBFT Tuning Box System
I guess that's for your car, isn't it?  My colleague has got an Audi A7, and he's had it "black boxed" from tdi-tuning by for 13 months, done 23k miles, no issues and he's very happy.  Apparently their tuning boxes don't just send false signal to ECU so that more fuel is injected (which f*cks up your DPF as result), but also modifies the air flow, i.e. adjusts turbo boost. So logically engine should have enough air to burn off all that extra fuel.
As well there are about 7 settings (minimum to maximum boost), so you get the chance to play around and find your best.
Might be worth looking at.
I'm tempted myself to get one of these, but on the other hand also thinking to do a remap instead, once the warranty runs out. Not that I need all those extra 40 horses (20 will do just fine), just want to get rid of the "stupid pedal" syndrome on low revs.

Cheers!

Talking about tuningboxes in the 108 (81 KW) engine, do remember that it´s restricted to 85% in the ECU.

This means that a proper chiptuning will, just by removing the torque-limit, bring it up to the 127/128 BHP also available on the i30 model range.

From there, its possible to raise by approx. 30 BHP so a proper chiptuning will send you 160 BHP /325 Nm

A tuningbox will not be able to get anywhere near this due to the 85% restriction.
