Sorry about the late reply guys, didn't find much time to surf and talk about our twingos lately.
Everything's is pretty much the same on my little baby, I would love to do so many things but the lack of money stops me
Have any of you made some interesting mods?
To reply to the previous questions, yes I think is worth to change the intake with a better/sporty one, I wouldn't go for the rock bottom brands thou, I don't know, I think since isn't extremely expensive is worth going for brands like K&N, I've got a Ramair and is good too.
Change only the intake won't give you much more power, only 1 max 2BHP, and will mess a bit the air/fuel mix (in all gears there is a better response but my max speed is now lower than before, but should be corrected by changing the CO2 settings on the ECU), but will give you a great hiss at high revs, a tiny bit more torque and a good 10% fuel economy -when you drive sensibly....
The ideal would be to add also a full exhaust, perhaps also without cat, and finally remap the ECU to work the increased air-fuel flow.
That's supposed to be the full phase 1, at the end of which you should gain about 10-12BHP..
