My LB7 has been throwing these codes for a while now, the first two codes are P0405 and P1404 which are EGR sensors. My question is this would having the PCM and taking it to someone to reprogram it eliminate these problems? If so do you all have any info on a place in S. California sd to oc. Also if I do reprogram it can the speed calibration for the axle ratio and tire change be programmed to what I have and can they eliminate ABS sensor light that comes on due to the change in gear ratio. What other modifications should be done to the PCM if any?

Also I am throwing P0234 which is an turbo overboost, PPE has a overboost code eliminator which claims the following for $229.00 -

Features:

• To prevent Over boost Diagnostic Trouble Codes P0234 and P0236 from limiting your engine.
• Don't let your engine be held from its full potential. Eliminate your over boost defueling during Full Throttle and Part Throttle to get maximum performance out of your engine with our LB7 Over Boost Code Eliminator.
• Plug-n-Play module with two simple connections under the hood.

Has anyone used this with any sucess? Sorry for asking so much appreciate any feedback!

When you get your P0234, do you lose power? If not, I wouldn't worry about getting the code eliminator unless it happens all the time. As far as reprogramming for the EGR valve stuff, you could find someone with EFI Live to disable it.

Well here's the problem several months ago I noticed a power loss with the code when pulling my Toy Hauler since then I guess I have gotten used to the power now. Don't get me wrong it's still has power but doesn't feel like it once did and the engine light is always on from start to end. At one point it would go away every now and then and the difference in power was quite noticeable but that has not happened for a while now. So EFI Live will eliminate these codes without actually running there system? Thanks for your help!
