What do you guys think of purchasing preprogramed PFC? Like from SRMotorsports. I assume you supply info on your mods and they set up PFC from there. I assume once this is installed it is best to take car for dynotune anyway. I am obviously new to this so info or links much appreciated. Thanks

 

You can save yourself money, by reading everything here, then setting it up yourself.

Wished I would have done that.

 

Don't tune by mail, it doesn't work! Use a map safe for your mods, then take it easy and find a dyno. The only real way of doing it. You could also get a datalogit and wideband and do it yourself with a friend on the street.
