Your car was being ran into high RPMs with no pressure at the intake mouth. I wouldnt be surpised that your DME started pulling timing
Thanks for the feedback. I too noticed this after the first baseline run, but in the interest of not adding another variable in the before/after dyno runs, I didn't want to change the fan setup and give the CF intake any additional benefit.

With that said, I've come to accept that all the dynos within 500 mile radius of me don't have any fans which can replicate the air CFM's the car will experience while on the road.

The only dyno that I am aware of that can, is the MAHA LPS 3000, which has an air fan accessory which can be purchased along with the dyno. It is a beast of a fan, looking like this:

The closest MAHA dyno I am aware of is in LA...

When I said it was depressed, I meant it was enabled.

With all due respect to the tuner I dont think he had much experience with an N54 DCT. There is alot of errors in that dyno.

When i dyno my car I request that xyz should be a certain way, your the paying customer.
You may certainly have a point, as this was their first N54 on the dyno, let alone N54 DCT. Either way I will accept the overall results considering it is a Mustang dyno, and the CF intake did show improvements.
