Is this a good opti!
But unless you payed that 600 or 531 I wouldn't worry it will still do its job. The GM performance parts opti sells for 299 in summit.

When I bought my last one, MSD's opti was not released yet. I got a brand new stock one for a steal from somebody that ordered the wrong one. I dont have near the problems that everybody has with opti's however. (The only reason I replaced mine was because of the fact that I could not find the problem.) (Turned out to be an intermittent coil problem believe it or not)
