need nitrous help badly
You arent giong to want to use the hypertech with nitrous. The hypertech advances your timing and that is bad for nitrous. Nitrous needs to pull timing to avoid KR.
Accessories you would want to look for are a fuel pressure safety switch, a window switch, blow down tube, and a nitrous filter.
From everything I've seen I like NX, Cold Fusion, and harris speedworks (although their solenoids are small and can't take very large shots without upgrading)
