FPR Spring Upgrade Verdict?

So what has everyone concluded on doing a fuel pressure spring upgrade?? I'm did the bb a while back but it disappeared somehow so I was wondering about just buying an aftermarket spring but didn't know where you guys were buying them at?

I am going to drill out the banjo bolts as well for increased flow and drop the tank to delete the screen and put an inline pre-pump filter in.

I am getting a slight miss at idle every three to five seconds or so and an intermittent miss at lower rpms no matter what gear the truck is in.

Where did you guys buy the spring from?? I don't want to loose another bb . . .not sure where it went either . .

Just get the RiffRaff FRx and be done with it. I just got done installing it on mine and the engine is way smoother, quieter, no more misses and the #8 injector noise is gone.
