G'day all,

The above posts are right on! I spoke with Roush today and indeed the issue concerns springs. Roush informed me that the newer motors already have the fix in place but for older motors it might not hurt to order the parts or contact them so that they can do a bit of investigation on your particular motor.

I earlier mentioned that the highest octane readily available here in NY was 91but in fact it is 93. Duh...
