I have some suggestions:
- Get some operational logs on datazap. Post the URL for us to see them.
- I'd flash back to a stock map and see what happens.
- Tell us how your car is set up mod-wise, also mileage, etc
- What happened with the car between, say, beginning of the year and April when it showed up? Mods, maintenance, daily driven, sat in a garage, et cetera.

I've owned the car since day1. I've maintained it to a T since day 1 as well. The car has all of the following mods (just pertaining to engine). In Fall of 2017 I started running E50, and since late April 18' I switched to 93 pump due to my issues since.
Car has 114,400 miles on it with original turbos. Turbos are strong and it's daily driven too.
Custom Tune 93 pump MHD (currently)
AFE GT Magnum cold air intake.
Fuel It stage 2 LPFP with E85 sensor
Eisenmann axleback
VRSF downpipes
New Coils 9/17
New Injectors 7/17
Plugs last replaced 9/17 (new ones in transit)
Walnut Blasting (2/18)
Berger Oil Catch Can installed 2/18 (no oil in can at all)
I had the clutch and flywheel replaced in 3/18. After I recieved the car back from the shop, that's when all of this started. I first started getting Fuel Pump plausibility code, I brought it to a mechanic and from there he said the charge pipe blew off when he was test driving it. He re-tightened everything up and made some adjustments to some engine pipes and hoses and test drove fine after. That code never came back for a couple weeks until a map revision was uploaded by tuner. For 2 months I ignored it because Steve from Fuel it said it was normal, especially with running E50. He checked my log and was good. I also replaced the fuel pump regulator and LPFP sensor too.
In early June I brought it back to the shop where they did my clutch job. They replaced some hardware pieces for the shifter and checked for any issues regarding to my symptoms I've been encountering. Mechanic did a boost leak test and reviewed everything, but not sure if he did a fuel leak test. Nothing came of that visit. A week after codes 29f4 and 29f5 started showing and still are present til this day. Thursday I replaced the pre-cat sensors and issue is still present and codes. I'll switch back to factory map tonight and see what happens.
