99blacksesport,
Thanks! Well mods go ported MAF ends/Airbox cut out. That is it for the Auto Z28
I know 13.8-13.7's with better tires alone! Then other mods will come next year

Nothing more than custom catback, Pully, Power programmer. That should yeild me into the 13.6 area for sure! I am even thinking a Cat Deletion
I know some guys have jumped stall's to 2800/3300rpm stall's and went 13.1's-12.8's with simular mods.
This is a lot of tweaking to go. But this is all I have done and was pretty happy to see my times.
Thanks for asking!
