The VA180 stacks well with the Predator so far, the Predator(2.02) is on the Max setting(100). Occasionally, but seemingly only when its cold, I will get slight bursting at the 3-4 shift. I do not have lift pumps yet but plan on purchasing some very soon.
I am sort of set on the Hot+2, though do not ask me why. I suppose I will get it and run it with the VA on 90, or I may run the Hot+2 on a lower setting and keep the VA at 180, or maybe even drop them both down to lower settings. I'd hate to keep them both at lower settings, feel like I'm not using well spent money.
As far as the VA180 having noticable power and making a difference, it definitely does. It helps on the low end but very minimally. The top end however is no joke. In 4th and 5th it picks up and takes off, has way more power than ever before, no turbo lag whatsoever, and great responsiveness. Its been said before, and I would definitely have to agree that the VA180 really shines on the top end. More of a freeway mobber box than a drag strip box, IMO. But that may change when combined with the Hot+2 on the right setting.
