I was not aware the standard engine would take boost at standard compression, I would be lowering merely as a precaution?
The standard ECU can be mapped to work with boost. just need a map which reads postive pressure.

I've seen it! someone did it with their red C2


compression isn't a huge factor, fuel type, quantity, air temp and ignition timing I think affect how much boost you can use more - things which affect knock. I'll get corrected no doubt, I'm pretty clueless. I'm a diesel man at heart and i upped my compression to 25:1... with boost

Really? I'm sure someone could do it, but for the time and effort (and effectiveness) I would probably still go standalone unless it is considerably cheaper than a standalone.

25:1 on a saxo? wow!
That's nothing for a diesel, but I am surprised your saxo didn't turn itself inside out hahaha!!

Of course having your standard ECU mapped to accept boost is WAY cheaper. it'll cost you a sensor, some injectors and a day on dyno.

Yes 23:1 standard 1.5D, it's indirect injection

Oh sorry I assumed petrol!

I didn't think there were many people that could do it, if you know of anyone in the south east get them to get in touch!!
