Is there anyone in the Va/DC area that might be willing to help a member and review the work from upgrading my JB3 to JB4 w/power wire? I installed DPs, changed spark plugs and upgraded the tuner. 3 miles down the road, CEL displays, and engine malfunction, reduction in power displays on navi screen. Checked the work and I'm at a stand still. The code that I am receiving on the dash is 29F3 ( fuel pressure sensor). The car was driving fine until after the install. My car is a 5/2008 6mt build with just over 35k miles. Any help amd assistance would be greatly appreciated.

Have you tried pulling the JB out, to see if those codes stay or disappear?

I'd start by putting it back to stock ECU then clearing the codes.

Thanks for the input guys. Will be doing this tomorrow. As well as checking the lines amd hoses for leaks. I'm now receiving codes 2EE3 and 30FF as well. This is so frustrating. Is it possible that my car may need a new coolant pump with just 35k miles? I know it electrical and having the car for 6 years doesn't help. Any thought are greatly appreciated.

30FF seems to be a boost leak. The vacuum lines run along the same side as the DME, so I guess it's possible that one came loose during install.

Also, check the connection of the pressure sensor in the charge pipe.
