Every motor is different. I agree with all who say the stock tune is pretty stout itself. I know Uprev needs more development time with the platform, and have yet to do much with VVEL due to how much a replacement valvetrain costs.
I didn't get any added HP from a tune either, and my car just had intakes only at the time.
