What calibration to use with Vortech FMU?
I have a Paxton SN2000 that I recently installed on my 92 Z28 that is an un-modified Tuned Port 350. I am going with a Vortech FMU and would like to ask what calibration disk I should go with. I have both 6:1 and 8:1 disks. My boost is at 5 to 6lbs. Thanks for any help.

hard saying I always did it on a dyno. start with the bigger one and keep an eye on the O2 volts and the knocks.

I wish I had the luxury of a dyno tune, but where I live this will be hard to come by. I think the closest facility to me that can do this is about 5 hours away. Thanks for the reply, I will try the 8:1 first and see how that does.
