Hey Ya'll, long time lurker, first time poster. I have searched this issue and haven't found enough info to act so I'm hoping someone can help.

I have multiple issues coming out of my truck. It really all started with the old factory POS cold side hose splitting. I replaced that with the S&B cold side kit and everything seemed to be working fine. Fast forward about 6 months, a new set of batteries, and now a whole string of issues has arisen. The truck cold starts fine and runs fine in the mornings. I drive about 50 miles to get to work and then park (no trailer). When I got to leave work to drive home, everything seems to go awry. When I try to start after sitting all day in the AZ sun, it shows a maxed out 40 psi boost gauge on the dash, and then almost immediately throws a code, often a different code but one of the codes listed below. I usually just reset it and then it seems fine for a time. By time I finish my commute, a new code or noticeably reduced power and fuel economy have occurred during the trip. I was averaging around 20 mpg before this started happening and now I can't seem to top 17.9 mpg. Sometimes the truck will have a dead feeling while accelerating followed by a quick slam with power coming on all at once. I have replaced the MAP sensor on top of the intake manifold (heavy soot build up on the old one), checked and re-checked the couplers for the new cold side tube, and checked for oil in weird places. Nothing appears to be out of the ordinary. I am going to remove and re-check the MAP, MAF and AIT sensors Saturday to see if there is any excess oil buildup that could be affecting readings. Some other goofy things I have noticed is every now and again the backpressure will seem to be off (high). It seems to not come out of boost under zero load as well (according to the Idash gauge). It gets worse during regens. It will spike from 1-2 PSI of boost to almost 10 psi when I let completely off the pedal on the freeway around 65mph (reads 0% load). The range of codes keeps things strange with anything from EGR valve reading out of limits to incorrect manifold pressure readings to turbo boost control circuit incorrect readings. I have also noticed the battery voltage will be off from time to time, reading from a healthy 14.6 volts while running to sometimes down to 13.3. It changes every time I start and run the truck. The only true modifications to the truck are a Banks Derringer tuner, new batteries, 35" tires, Banks Idash, and a couple of amps/sound system(grounded on the pass front floor). Before I order more parts to throw at the issues, I wanted to check here. CCV? Electrical issue? Sensor Issue? EGR Clogged? Exhaust Backpressure Sensor?

Codes:
P00BD
P2263
P04D9
P0069

TLR Truck has lots of issues, ran like a top before factory boost tube blow out and battery replacement.

This is driving me nuts, so anyone that can help before I throw $$$ and time at the problems is much appreciated.

 

check your sensor data at different rpms

you can go to this thread and around post 25 there are screen shots of IAT, MAP, EBP, DPF Inlet, MAF, etc at different rpms ......take note of the EBP sensor . cleaning sensor that are worn is a waste of time...if your sensors are out of spec...replace with motorcraft

for the p0069.....you are not going to like this...the first thing you need to do is remove the deringer....either get it out of the loop and connect the idash directly to odb2 port...or use the dongle you got with the derringer and disconnect the wire harness from the derringer and install the dongle to the wire harness. there have been cases of p0069 codes being caused by derringer. other soruces of the p0069 is anair leak on egr tubes, air leak on intake tube mating surface to engine, spooky bananans with throttle body. if the problem is due to derringer ...call banks and explain you have a p0069 at key on even if you reset after last engine run....they may have a remedy for you.
