Is a NW 90 TB better than a FAST 90 TB?

If the stock bolts will start in the hole, then FAST used a 4mm tap. I think the thread pitch is .7

I have a F.A.S.T 90mm and it is garbage...nothing but a big fancy ashtray now. I had to run a throttle return spring just to get the plate to shut and the car couldn't be tuned properly with it. F.A.S.T sent me a rebuild kit for $75 and it still didn't fix the problem. I can't believe they get away with selling a product for almost 3 years that doesn't work.
I was thinking of going Holley but I think i'm going to play it safe and go NW.
