A slight derail here, but...
Is a remap worth while (or just silly) on a stock 1.7?
The issue is, that here in Spain, everything must be declared and aproved by the ITV (equivalent of MOT). For it to be approved, you need to present documentation of the part, a certificate saying it is valid for your car and/or a study and project made by an engineer, and finally a certificate from a garage saying they installed it and that it is safe.
I am actually lucky in part, because my brother is an engineer, but we still have to pay the taxes etc. which can be between 300 and 700 euros, depending on what you are "legalizing". So, the cheapest way is to collect the parts you plan on changing, then get them all fitted and "legalized" at the same time.
Obviously, there are certain things that are not detected easily (such as an engine remap) and can be done over time, and then presented on the paperwork at the same time as all the rest.
On a lot of cars, I have fitted universal chips, and as I have fitted other parts, remapped the engine to find the "sweet spot".
Is this something that is possible on a Puma 1.7?
Thanks as always.
