This has been a journey.
Well impressed with your determination absolutely awesome.
This SP63 build looks and reads so far to be the dogs nuts.
I read the SP63 write up on their site just which where great, but more importantly I’m looking forward to your results using the NX2 as a real world car with real world results

Sounding all good looking forward to you finishing your break in.

I did the break in and ran about 1300 miles went for a tune and was told it needs another 1000 as the engine was still tight.

After the extra 1000 the tuner magically added another 27bhp giving at that time 439whp.

So basically you may need additional mileage to loosen the engine

Headed to Europe and Egypt, back 20th to resume tuning.

I have been thinking of putting a sport cat in.place of catless downpipe.

is a sport cat just as loud? anyone tested
I can vouch for going sports cat from OEM. It’s louder than the OEM as it flows more air but wouldn’t think it would be as loud as going catless

The Bosch HPFP pump works a treat.
I haven't ran out of fuel pressure and it feeds 4x GDI injectors and 4x 1000cc AUX injectors.
A big bonus is the car will run so you can at least get it to the tuners to map it all in properly,
as I think the XDi pump leaves you dead in the water.

Well worth it :)

AND its BOSCH with reliability which the XDi hasn't got close to yet.
