Have no dog in the race, but as a GTM kit owner. I know it took 6 months for them to ship it, but I wasn't the one that had to wait. I'm happy with my little 8 psi stage 2 setup, but I will not purchase a product from them until it's ready to be shipped.
Take in mind they're plenty other options now for FI.
