Help!!
I had Dynatech long tubes and cats, Speed Inc CAI, 160 t-stat, for mods and I ran a 12.9. To get that, I had to launch at idle and not power shift 1-2. If I came out hotter than idle or shifted 1-2, it would just blaze the tires.
So headers and CAI for me, netted .3 seconds over my best bone stock time of 13.25.
