After popping about 5 FRPSs on my NA/Nitrous motor I installed the KB restrictor and I have not had that problem again and based on my WB AF monitor I dont see any changes in the response times.
So IMHO well worth the 5 bucks!

I did this because I had the in-between-shift hesitation and nothing got rid of it (until I pulled out the PPRV). The result of this is that when you're WOT and lift, instead of the PPRV valve cutting out the excess fuel flow, the fuel pressure will spike before the FRPS can tell the FPDM to pull voltage -blowing the FRPS. I'm sure other modifications can cause the same thing. Once I put the KB disc in with a new FRPS and unplugged the battery for an hour (to reset the tables) I have not blown another FRPS, and my car is a track car so it gets beat on 80% of the time.
As far as the response time and pressure I have datalogged it, before and after and I see little difference. For $5.00 and shipping this is a very inexpensive solution. Also remember that FRPS's have a given tolerance, so try at least 2 before you try another solution, you could have a crappy one to start with!
