Nitrous Questions for 99GT

[Swarzkopf]

Hi, long time reader, infrequent poster here with a few questions I hope you all can give me some answers too. I'm seriously considering a 100 shot for my 99 GT, automatic. I've heard that the Nitrous Works makes a good dry kit. Here's my questions:

1. Nitrous+automatic- With a 100 shot, would it be safe to spray through each gear shift, or should I disengage the nitrous before each shift?

2. Fuel system- From what I know, the returnless fuel system on my car becomes a real pain in the *** when power adders become a consideration. Would a new fuel pump/injector deal do the trick for me?

3. Availability- Where can I get a kit designed for 99+ GTs? I usually do my business with Summit (they're real close to me), but they don't have anything listed online.

Okay, that said, are any of you spraying on a newer GT 4.6L? Any other tips? What times are you running? I expect that a 100 shot+bolt ons on my convertible will land me close to 13.0...

Thank you!
