Get the manifold, head to UM for custom tune. I have a Golf R IE manifold owner who swapped to a UM tune with the manifold. Granted, he hasn't faced winter cold starts but we'll see.Why not reverse engineer anyone of the flashing tools already on the market? Seems like a no brainer.
Or just start with mail-in flashing. It seems everyday you are losing potential customers from an already super saturated market pool. I was one of those customers you lost. I really wanted to wait for the 2IMko4 software but shit took to long and I went BT. I would however consider your manifold if you started making big turbo software.
