Can they both be used in the car, and would there be any benefits? My friend might have an extra one for $130, i was thinkin that is too good to pass up.

 

it would be redundant. just pick one. preferrably the tuned piggyback if you're lightly modded. you could hypothetically hook both of them up, but it's kinda strange modifying a modified signal.

 

well i already have the piggyback, and i was thinkin that it would also be kind of pointless, but since i could get the s-afc so cheap, i thought i would get some other people's opinions.

Thanks for ur help.

 

what you could do is spend that $130 towards getting software for the piggyback. it's another idea. the piggyback is a better unit than the safc anyhow.

 

what kind of software?

 

if you have the rrm piggyback, www.splitsec.com is the site. you'd have to find out through them about buying the software or maybe ask rrm. it's an option if you're serious about making adjustments in the future. the RRM map is pretty good as it is.
