The Elite 1500 is now running fine after having problems with the home signal. It seems both one of the wires used from the distributor is bad as well as one of the Haltech E11v2 wiring harness. After repinning both the home sensor connector and the Haltech 26pin connector it works fine now.
Road tuning will follow as well as swapping the front swaybar back to the OEM one from the C-One to only have the stronger C-One in the back which should help getting rid of the slight understeer.

Any updates with this? Tuned yet? I'm curious to know how you find the increased displacement and new turbo. How common are ST205's in Europe? One day I wouldn't mind importing one from Europe to Canada so I don't have to deal with right hand drive imports as they are commonly brought over here from Japan.

Road tuning by my engine builder and Haltech tuner showed problems with the boost control. He suggested to change to the strong 1.2bar actuator, didn't help, suggested to change to the Turbosmart IWG-75 dual port actuator, didn't help again. He suspects a clogged or otherwise to restrictive catalyst converter but I hadn't had the time to get it on a lift to check that.
It reached 1.8 bar @4000rpm but quickly fell off to about 1.2bar.
Still enough to close in on a Porsche Cayman GT4, overtake it and outrun it at 275+ km/h. :D
The goal is still to reach 300km/h.

On another attempt the boost problem was found: the Catco cat which came with the 3“ Aussie frontpipe from Fensport is a ceramic one that‘s only good for about 200HP according to my tuner. A larger, better flowing HJS cat is ordered and should finally fix the boost control problems.
The engine was only able to get to about 1.2bar above 4500rpm so I‘m super excited how much the new cat will improve the top end.
