what is the best system that I can use on my car besides the JWT? I know there are a bunch of 4 cylinder kits out there, but I want performance, also how big of a shot can I use before I lean it out, also would a regulator work with NOS? I know that they do not work too good on n/a applications, but with a bottle would it keep it from leaning out, so I could use a bigger ****? Reason being is that I am probably going to be in the market for a system within a month or two, so I want some opinions. (just a crutch until I get the gti-r engine Jay, NOS master?
