What AFPR are you using?
I was wondering what AFPR most people are using? How do you like it? Is it easy to adjust? Are they bolt in for our cars, or do you have to saw the stock regulator and bolt these on? Thanks.

got myself a holley afpr... didnt have to saw anything, lol, just had to take off the plenum, unscrew the fpr, then put the holley afpr and i was set.
i had it set at 46 psi...
then my friend and i were working on the car, and he raised the fp to see if it would net me any more power. i really didnt feel any difference, but an something happened at my house that made me forget that i had to turn back down the fuel presure.... later that week, i blew my motor because the fp was too high and i gas washed my rings
