Hello all,

Greetings from The Netherlands!

After driving a 350z for 4 years, it was time for something new/faster. I bought a 370z 40th anniversary with Stillen supercharger 1 year ago with also the intention to learn more about cars/mechanics, kind of a car noob at first... and still, but less

. Mostly stock component besides the Stillen SC kit. The car had 440whp but was not very stable, running very rich, tune was bad etc.

I upgraded some parts already, like:

- SOHO air to air kit
- Fuel return
- Single Walbro 450 LPH
- Greddy dual exhaust
- Denso GTR injectors
- GTR Map sensor
- Gauges / meters
- Some small parts

After that I went for a new Ecutek tune from the Z-god in Germany (CTD-Germany). Car is almost finished but need some tweaking in the tune, the high RPM range is still too lean (above 6500/7000 RPM). We will try to boost fuel pressure or worst case, replace the injectors with bigger ones. Hope one of these will resolve the issue.

Overall happy with the results so far, around 10-11 PSI which is good for now. Will do dyno after the tune is complete but we think around ±520whp now. Ofcourse there are more plans on the way (also exterior) but for now I am okay!

Hope to learn more on the forum from you guys, stay safe.

KR, Emile
