Midwayman - you and I are on the same brain wave!
It's like I'm asking the questions and starting this thread.. but it's not me... hrmm..(btw thanks for the info in the thread I DID start.. )
I feel the exact same. I want to get the NA cams.. but I want to do it right and not just 'get by'. (Use a bandaid here and a piece of gum and viola!) I am eagerly awaiting answers to your questions and if you can get this straightened out.. I will probably be following in your footsteps..
I might just have to break down and contact Cobb for answers on this since I will be going through them for the cams and install. Only problem is, I feel guilty calling the with questions. Especially, since I haven't commited to buying the cams yet... just another newbie calling and probably asking the same questions everyone else is... hehe.
"I pity the foo!"
p.s. Don't mean to derail this thread.. but what's the difference between FPR and RRFPR? FPR is a constant pressure increase while an RRFPR increases pressure in relation to a change in vacuum pressure?
