The 2004 Stillen catalog shows an ECU upgrade for the 350Z. The part number said "TBA" and it didnt have a price. The last time I checked it wasnt on their website. Anyone have any info?

 

I was at the Stillen convention last week and there wasn't any mention of it. Probably still in development.

 

If you are taking about their piggy back unit, it is just the Perfect Power SMT6 with a Stillen made map. Of course the map is probably password protected and who knows what mods it is good for. I did some searching regarding this some time ago. You might want to search my posts.
