ASP Pulleys

[AZ1500]

I'm considering installing underdrive pulleys on my 5.3. Harmonic balancer and the alternator pulley. Has anyone experienced the pcm throwing codes after installing the pulleys. The shop that's doing the work says no, but I'd like to hear from someone who's done the mod.

This is the setup that was recommended to me last year:

 

ASP Pulley Kit

ASP 549900 ASP Harmonic Balancer Crank Pulley

ASP 540120 ASP Overdrive Alternator Pulley

KO608882 Gates Belt

KO403345 Gates Belt

Are you running that combination, and if so, have you got any codes?

[The SPEEDY]

You should not get any codes.

I never ended up getting them.

I haven't read about getting codes with that setup.
