ND-Photo.nl 's - Seat Leon ST Cupra 280

[nd-photo.nl]

Decided to get the Cupra mapped in July 2025. Went to a smaller company called Performance Base, which is located 20 minutes from me. He was recommended to me by some people I know.

I didnt want anything extreme and went for a Stage 1+ map combined with a Stage 2 DSG map.

Results:
296 BHP > 381 BHP
378Nm > 524Nm

He mentioned that the bigger downpipe resulted in the horsepower bump to almost 300 BHP in stock form It'scrazy how a bit of adjustments in the software can result in such big changes

Getting the Cupra ready

His mapped Audi S3 limousine in front (about 420 BHP)

He uses DynoPro, so the car is tuned on the streets. This device on your wheel bolt is combined with OBD data to get to the results

He noticed that there was some irratic behaviour sometimes and asked which plugs I used (Bosch). I was recommended these NGK plugs, which I ordered off course.

Type: NGK Laser Iridium ILFER7C8EG 91898

I posted this on Instagram hehe

Its crazy once you get the results visualized

Well done welcome to the Stage 1 Club you wont regret it.

Many thanks! It's crazy how much the car changes with just some software adjustments

For anyone contemplating a stage 1 chip, do it!

To replace the plastic intercooler pipes, I bought a aluminium hardpipe kit, which looked like a quality bit of kit

Quality of the bungs looking good

And then a little bit later, I received the NGK ILFER7C8EG 91898 Laser Iridium spark plugs that the tuner recommended

The difference in the center electrode is clearly visible. The NGK has a sharper electrode

This is how the Bosch spark plugs looked
