Just a few lines to give you my impression of a tuning box fitted to my car. The box was bought from ebay new at

Analogue box >>> not gonna get the best results as you end up overfuelling. Also, did you put on a cupra intake as otherwise it will just be smoking a lot. Sure it will be a tad faster too (actually that's not bad at all imho).

A second faster in the 3rd/4th is decent for 30 quid.

A proper tuning box (digital) will probably get you slightly better results, not much though, but it's not gonna cause errors showing on your ECU. Analogue ones can cause overfuelling to trigger an error code.

For 30 quid I think you got pretty decent gains really. A remap does more than just alter fuelling though, it also messes about with turbo pressures and can give you a very tailored behaviour.

Especially the Custom Code '1' seems to be very smooth at the moment, and they are expensive for sure, but you get what you pay for to some extent.

My opinion is that a cheap analogue box is excellent value for money based on your results. The next step up is gonna cost about 10 times that amount minimum for a Dragon digital tuning box say, and it goes even higher for a remap, think the CC1 was 450 quid but cant remember if that was incl. VAT and stuff or not.

I would definitely stick a Curpa air intake on though

I've read the threads on the cupra intake but the car is only a year old. Will it affect the warranty?

I doubt it, if you did have to make a claim swap back to the original...

And lets face it, why worry about that when you've just stuck a tuning box on it anyway, which in theory also invalidates the warranty.

Was just gonna post that - your warranty was voided the minute you put the tuning box on it. Basically that would be warranty on the clutch and engine mainly in reality.

Yes I know the wrranty will be void with the box but it only takes 30 secs to remove it. I might fit the intake anyway because my mate was following me yesterday and he says when I put my foot down there is loads of smoke.

That's the problem with analogue tuning boxes anyway - overfuelling. The cupra intake will make the situation a LOT better and I would highly recommend it. It won't completely get rid of the smoke but it should reduce it significantly

No cupra intake here and no smoke :P Do we have any hard evidence that the cupra intake is beneficial? I thought the VAG-COM tests that someone did showed that there was no difference? :confused:
