Something's different...

At the moment fairly low boost, as the injectors will be running out of fuel too early if I run too much. It's around 7/8psi at the moment which at peak power 7k the fuel ratio is at about 12.4 which isn't too bad.

That turbo with uprated fueling system and new ecu which can be completely customised rather than use a piggy back device is good for in excess of 250bhp. But when you get to 250+bhp you need to change the CR and do a little bit of engine work to cope with the extra power.

I'd have loved to have bought a new ECU but it was a bit beyond my budget for the moment. When I can afford it I'll sell the piggy back and get a compatible plug in ECU - which are available for the mx5.

if you are going for 250bhp + then its a good choice. it seemed as thought you were mentioning 200-230bhp as top levels.

Well one thing at a time. Happy to hear suggestions though.

I doubt I'll do much more tweaking for a little while. I actually bought off ebay a GT25, which might be better - anyway you live and learn!

It basically "taps" into your normal ecu adding a few extra bits of functionality/programability, like fuel/air ratio timings etc...

Whats the import duty like from the US?

Sorry dude

It's not too bad in general but as ever there are ways of legitimately not getting too ripped off. There are also people who mass import the stuff so you can purchase them within the uk.
