I have a C&L intake and xcal 2 tuner coming from Breenspeed next week. My question is if I install Steeda's udp's will I need a new tune from Breenspeed?
Im kinda thinking I should have gottenthem before ordering the intake and tuner.

 

no

 

I guess Matt didn't feel the need to elaborate, but he's right, you don't have to have a special tune for UDP's.

 

keepyour factory pullies for when you upgrade to the twin screws

 

??? Semi related to this subject....why is it that you can not use the UDP's with a Blower? I don't see how this would affect anything.

 

The pullies would be "underdriving" the SC

 

then why not just get a smaller blower pulley?

My s/c t-bird has a 3 belt setup so i could run UDPs and not affect the blower
