Posted By: Airbornec507 On: 10-31-2009 @ 16:26:24 Reply | Top | Edit That's a healthy cam.....is it SR or HR? I know you were talking about your heads in another post. Did you decide to send them off to Lloyd or go another route? If so that sucker will love some high rpm sucking tons of air. Should be a very interesting combo. --

Why spend all this time and money on a motor and cheap out on the tune? Its the most important part. -- 2005 CTS-V LS6 M6 13.627@105.14 stock and hot/humid  Posted By: cmerc On: 10-31-2009 @ 18:56:32 Reply | Top | Edit Jeremiah, thats true, so help me out here, give me the address of a good place in florida where I can have the car shipped to from Nassau Bahamas and I can have it done. As an alternative package Harlan up in a big box and send him to me FedEx I will give you our account number and address, send him overnight express that way he will just need some water and pringles till he gets here. --
Posted By: lt1_fool On: 10-31-2009 @ 23:04:03 Reply | Top | Edit I've got a tune for a 383 stroker w/ 12:1 compression. Shoot me you gear ratio and injector size and I can get you really close to where you need to be... The fuel and timing map should be very similar since your setup will be so close. --  Posted By: Jeremiah On: 11-01-2009 @ 10:56:02 Reply | Top | Edit I forget you are in bfe..lol -- 2005 CTS-V LS6 M6 13.627@105.14 stock and hot/humid Posted By: cmerc On: 11-01-2009 @ 15:02:51 Reply | Top | Edit ^ sooooooo what!!! you ain't sending Harlan  --
