so i went a couple months ago and ran corrected
12.60 @ 107.67
12.56 @ 107.70
12.52 @ 108.29

wanting more TRAP so i
- put bigger tube & upgraded to dual brake-duct feeding the volant
- pulled the 2.75" borla S catback and put a magnaflow(12579?) muffler which measured a true 3"
- put the UDP on
- revised tuning with these mods

and last night i ran corrected
12.47 @ 108.24
12.46 @ 108.27
12.56 @ 107.43 (sat in line running for a long time)

the worst part is that the truck feels significantly better on the butt dyno up top ??? pretty disappointed.

You're pulling timing. ;) I have a low mph for my et too.

The computer calls for your time of 12.46 to have a mph of 108.50 so your just about right.

Your 12.73 calls for 106.30 mph

It's just me then. :p I shall use my tools for success and try again!
