Re: Injectors and AFPR

["Dave Zug." <dzug@delanet.com>]

Adj regulator is worth it for GM just for the improved spray pattern that
the slightly higher pressure offers. You need to adjust what the computer
thinks the injector size is slightly to really get the benefit.  Another
plus is the ability to *slightly* tweak at the track based on conditions
using a wrench insted of a chip burner.

Another reason to get an adjustable regulator is if you've made slight air
side mods and want fueling to change *slightly* to match, without doing
computer work.

All in all, worth it if you use it right, and don't mis understand what it
can do for you.
