I have fix the D1 VS just now!
So far the item works as what it was claimed.
(Voltmeter 13.8 before start engine.
Voltmeter 15.0 when engine start.
Voltmeter 14.2 when all all devices on including
powerful sound system on.)
Will now monitor on the performance......

Yo bro.....

I've just installed D1 Spec VS with 5pt grounding by SPC. Why not? I've heard a lot of VS but the D1 Spec attract me the most. Other than the 40000, it is made in Japan.

What can I say, my feet did the throttling is faster than the mouth do mouth talking. Whatever Yamasaki wrote is really what i experiencing right now with my spectra.
1. My vehicle seems more lighter ( from pickup to cruising )
2. Smooth in shifting gear.
3. Engine noise lesser
4. Ur sound system clarity improve
5. Headlight & Fog lamp slightly brighter
6. FC slightly improve and still monitoring.
7. Installation on site.
Since this is my first VS, i'm fully satisfied with the design and performance by the D1 Spec.
Just go for it brother.

Installed D1 Spec Voltage Stabilizer on Sat. My car seems to be more responsive especially on the lower rpms, bass got more punch, car felt lighter on acceleration, OBC shows lower per L/100km and nice box with blue 'neon' lights and voltage reading when engine is running.

Happy with the mod which I think for that $1xx, you can get some improvements especially on the electronics, like Whisky Tango mentioned.

my two cents worth....


we are now offering D1 spec at a special rate due to the incoming Chinese new year season.
