I am definitely enjoying it! Not entirely practical - but I can live with that
I've not had it remapped yet; the manufacturer and supplier of the manifold (FT86 Speedfactory, in the US) implied that while it's certainly better to have it mapped, it can cope without one perfectly well - but a mapping session is something I'm saving up for, and plan to do it as soon as reasonably possible. I must admit, I'm not committed to making maximum power... I'm just(!) looking for the nice burble, and hopefully my set up is similar to some of the videos I've seen on the net.
As for the recall - I dropped it off this morning. No Supra, as you said; I got a Yaris instead. An automatic Yaris. It is a petrol-hybrid though, so it's quite interesting just wafting around in utter silence. Must be what being inside a bubble feels like...
