Nitrous express questions with 100 shot and MSD window switches

Ok guys this is a simple question. I've finally bought the NX wet kit for my 01 gt. And I've been searching around on stangnet and have found that some people are leaning out when running NX 100 shots. Is this a common problem? What have been your experiences?

Also, I bought an MSD window switch that I thought I needed a tach adapter for. I was told by MSD that I would not need to buy a tach adapter because it is specially made by MSD for Nitrous Express for use on my car. Have any of you guys heard of this before? It seems most people need a tach adapter, is this something new? Just so you know, the NX part number for the window switch is #18959M

I just called and confirmed with Nitrous Express that MSD window switch with model number #18959M does NOT need a tach adapter for 99+ mustang gts.

are you running a wet or dry kit? and if you are running a wet kit then when you put it on take it to a dyno while you test the jets to see what your a/f ratio is. if it runs lean then just put in the next size bigger fuel jet.

on the window switch I know that you have to have a tach addapter for that, it has been that way since the 99+ body style has come out, unless msd has come up with something new which may be the case. if they say it doesnt need it then install it per the instructions.
