[Ecotec] Unichip and tune thoughts on this?

[Sonie]

I have a vs 3.8 auto, I want to put the heads of a vy l67. Just wondering what is the best way to go about it computer wise.?
Could I use a piggyback ecu with the original ecu? And if so where would I find one ?
Thank you

What are you trying to do?

You can't use L67 heads without the supercharger (they're exactly the same as Ecotec heads anyway apart from the injector ports), and even then you wouldn't need an ECU.
