I got recondmended by my shop guy to do it. He say's it's very important so you can see if your getting max boost.

I'm not kean on it, but if I have to have it...I guess so. Or if you guys tell me different.

Plus my shop guy gave me a estimate of 10 hours for install(mind you this is a high preformace aftermarket shop) they have installed sc's before, they know what they are doing. In my opinion, I don't think it will take that long....what do you think?
