Default Finally...

Got some dyno time lined up for tomorrow.

Nic D will have my truck for a couple hrs tomorrow at AZ Dynochip. Any stabs in the neighborhood of power?

Well good and bad news.

bad news-
NEED injectors (so if anyone has any take-out 8.1s let me know ASAP!)

NEED a PRNDL switch

O2s are preferred but not entirely necessary for when I go back but they need to be replaced

however, Cutting it at 5200RPM with a solid mid 12 AFR I pulled 322/325...

When I go back after I get some 8.1 injectors I will probably rev to about 6200 depending on where my power cuts.

Good news is Nic definitely took care of me and he thinks with new injectors it will put a solid 340 down. So Im pretty pleased especially running thru a 4L80 which now has a leaking out put shaft seal

Torque should have peaked by then i would imagine. Regardless, get those new injectors in and re dyno!
