Tuning isn't a problem.

As with any DI motor, fuel is the limiting factor once you set out to exceed 85ish hp per cylinder. At Aviva, we believe we can solve this problem in a simple, elegant, cost effective manner in keeping with the original design, but without its limitations.

Full Race makes very nice fabricated manifolds. Aviva prefers to provide a more OE fit, finish, and function, also without its chief limitation.

Choice is good. ;-) I look forward to seeing what Geof and his folks come up with.
