Hey guys/gals,

OK. I have a 2003 954 that I love. I currently have a bolt on two brothers exhaust (C2) on it with no other mods. I have the K&N in the box, but am waiting to purchase a Power Commander so I could install all of it at once. I'm also thinking about putting on some Velocity Stacks just for kicks. Will all this make a significant difference? Also, when I install my Power Commander, will I just have to download the map that has "Two Brothers Racing bolt-on exhaust and stock or aftermarket air filter" or will I have to get it done somewhere professionally because of the Velocity Stacks? If I do, how much does the tuning go for? Thanks for reading.....and ride safe....fun....but safe.

 

The power commander should be your last installation. Incorporate all your mods into your bike then find a dynojet auhthorized tuner and get a custom map! Thats the way I went and IMO you will never be happier!

 

Thanks Renegade1066. I appreciate your help....

 

he's right, do all the mods your going to and then install PCIII right before you go get it tuned, becuase by it self the PCIII does nothing
