2 questions before I start my TNT install!!

First is an easy one. Do I need to put TB gaskets around the plate that goes between the TB and intake mani? Second I need to get a FPSS, I was thinking about going with the N.O.S. 15685, which is a 50 psi hobbs switch. After searching around on here I found that NX makes a FPSS that a lot of people seem to be using (pn 15718). Is there a big difference other than the 20 bucks in price? Is one easier to install? Any other comments about the 2?

Thanks!!

sorry to scare you.....but ive had 6 problems with my TNT kit so far(its only been a week or so)

I hope it was just that the installed was reallllllllly messed up and not the kit,cause i heard alot of good things about TNT before i bought it

My buddy was running the LT1 kit on his car for quite a while and never had any problems, that's one reason I went with it.
