New Dyno Numbers

[lightitup]

Put my truck on a mustang dyno to make sure my mailorder tune was okay. They had to stop the run early because the truck was running way to lean.
A/F got up to 13.81:uh oh:

good reason to get a good DYNO tune instead of a mail order... especially on an engine that youve spend mucho dinero building... (unless its an amazon tune!)

Added video to original post. Looks like the problem could be a clogged fuel filter and not the tune.

Is it just me or did he do the pull in second gear?

After watching it, I think so.

Yeah I don't plan on going back to them. I will put it on a dynojet in my area. The numbers were on my winter tune at 14* timing so I am happy with the numbers so far.
