Peugeot 208 GTI 1.6T THP200 - Etuners Stage2 98RON + Scorpion exhaust 

We love the 208 GTi, even more so when it comes equipped with a full exhaust and ready for tuning. This car came to us in almost brand new condition, although it already had 25.000km. It was a 2015 model with EP6-CDTX engine (Euro5), that produces around 200bhp stock.
A Scorpion full exhaust had been installed to improve performance but because of the sports cat converter, P0420 would trigger the Check Engine Light on the dashboard.

This is a common problem with sports catalytic converters that come with aftermarket exhausts, because although their emissions make the car road legal, they are not good enough to keep up with the ECU’s cat filtration standards. The warning light is taken care of by our Etuners Stage2 ECU remap.

An Etuners Stage2 remap for 98RON was installed on the car, flashed via OBD with FlasherTHP. Power rose to 232.5hp from 212hp, together with an additional 31ft*lbs of torque over stock.

  • Etuners Stage2 ECU remap, flashed via OBD2 with FlasherTHP

Performance results

  • Maximum flywheel power : 232hp (measured on stock map and Scorpion exhaust as 212), gains 20.5hp
  • Maximum flywheel torque: 256.7 ft*lbs (measured on stock map and Scorpion exhaust as 225.8 ft*lbs), gains 31ft*lbs

The stock intercooler is the limitation factor for power output on a Stage2 car, since it overheats very easily.With the addition of an upgraded intercooler, the EP6-CDTX engine can reach 250hp very easily on 98RON.

Many thanks to the owner for trusting us with his beautiful car.

    I’ve bought a peugeot 208 gti from 2013, which have an upgraded intercooler and miltek cat back exhaust, done by the previous owner. A few times I’ve expericed an “Engine fault: repair needed” message followed by loss of power untill the engine was shut off. After turning the car back on the engine fault message would be gone and everything runs normally. The fault comes everytime it runs over 200 km/h and a few times driving normally.
    My local Peugeot dealer couldn’t find any faults. Do you think a remap could fix this problem?
    Best regards Mathias

      Hi Mathias. In order to get a remap, your car needs to run perfect and be healthy all the time. If you have to go remap your car to make it work properly, that wont do. Because it means there is an underlying problem that you want to cover, rather than fix. And this always ends in tears.
      First you need to fix whatever is wrong, then you can remap your car and enjoy the new fun out of it. Not the other way around. Tuning for concealing problems is like trying to compete in the Olympics with a heart condition: not a good idea.

    Love your stuff. Me living in sweden limits what can be done performance wise to my Pug 208 gti. How would I be able to benefit from your products? Is there a place on your site with your products and prices? Do you have a scandinavien dealer?
