From what I understand our platform is limited in hptuners, especially when it comes to the transmission. I am familiar with vince and trifecta tuning though. I saw a g8 on his website with the ly7 and it gained very little, so I suppose we are in the same boat?? I've also seen the member ztollon mention a megasquirt product??? What's our best option?

I'd like to run intake, ported throttle body, vmax spacer/ or upgraded intake manifold, headers, and a somewhat quiet exhaust system. I'm not sure the manifold or the headers will happen since the CPR6 is $1500+ and headers would have to be more $$$. But, with all this being done, I'd expect a tune to be essential thus my question.
