I'm battling here...2008 185 4.7L J05D-TF motor, just put a used motor in, starts instantly, runs like a top, but has no balls at all. It's been emissions deleted, fresh fuel filters, no codes, turbo seems to be working, it has to be fuel related but? It'll rev to 2500RPM, so its not the brake switch, but this thing couldn't pull a weiner off a plate. Ideas? Thoughts?

It's going to be difficult to diagnose without seeing what the ecu is seeing.

You can buy a Russian-hacked copy of DX2 off of eBay for $20. Put it on a Windows 7 laptop. Get a Nexiq Usb-link with a 16 pin DLC connector and you're good to go.
