Underdriven Crank pulley- Safe? Worth it?

Underdriven Crank pulley- Safe? Worth it?
I was looking into getting one of these but I never bought it because I read they were giving false knock retard from being unbalanced making the hp curve fall off early. I think it was mainly the SLP pullies but it might have been March and ASP as well.
As far as power, some people say it is a mod you feel, not a mod you see on the dyno but I see people saying they picked up anywhere from 3-9 rwhp with them. If you don't see a hp gain then all it could do to help is rev the car faster. I already have 4.10's so I really don't want the car to rev any faster.

Awhile back ASP came out with a better pulley & doesn't have a problem. I've got a ASP pulley on mine & the car charges good too. I haven't had a single problem with it.-Fred

Hello:
I traded in a 2001 Mustang GT in March 2003 for my poor forgotten Firebird LS1 Formula A4 sitting behind a local dealership, unsold, unloved.
1/4 mile times: dead stock 14.06
With used SLP lid And FRA mod: 13.81
I'm getting a pulley and I'll keep you posted on the 1/4 times.
The Mustang Gt w/AT went from 14.3 to 13.9 with a pulley, T/A and X-pipe.
The pulley seemed to help even down low, unlike many other high rpm mods.
I'll let ya know what the new times are like.............
