Hi, I have an 06 5.9 2500 Mega Cab with S/B filter, Edge programmer, and a Monster Ram intake. I have done other things to the truck in the way of , larger trans sump, remote oil filter, etc. and I have changed all the fluids in the truck to Amsoil. All of this to gain MPH. When I installed the Banks Ram my boost went from 18-20 up to 40-42 towing up hill when I get into it. Normal acceleration I get 25-32 easy. I have talked to a lot of people and most say it can't be and some say it is normal for the 5.9 and others say it is to high and I could damage my turbo or blow a head gasket. Even Banks techs gave me 2 different opinions. Any Help.

 

Do you have a pyro and if so what exhaust temps are you seeing when boost is high? What setting are you running on your Edge? Any codes setting?

 

What are you using to read boost? You may have had an boost leak before and corrected it during the install.

 

What he said ^
You might of had a boost leak. For 06 your boost should be at 35 psi.

Those boost numbers seem way to high. I agree check for leaks

 

I don't think he has a leak. He may of had a leak. I was asking if he was reading it off of the Edge or a boost gauge. The Edge uses the map sensor. Edge or the Map sensor may have went to poop.

 

Boost leak would keep the numbers down.

Hi Guys, thanks for the input. I am reading the boost of the Edge programmer. My egt's are 1250 at 40 boost. What about a malfunctioning waste gate? G

 

That makes sense to me but I have seen on another truck after a install the darn gauge would not read until 15 psi then would read up to 40 psi. The truck was 2001 cummins with only a edge and nothing else. My buddy was jacked for those boost numbers but I doubted it. after looking I found 2 leaks. after a little fix the gauge started working fine. Why it threw it out like that is beyond me

 

It is very possible. The boost solenoid could be stuck closed. I would think you would get a code for overboost if that happened. Maybe not while running the Edge product. On 04.5 and up trucks the boost is controlled by the ECM via the boost solenoid. It is the big black cylinder shaped thing on the turbo compressor housing.

 

I changed some settings on the Edge and in #3 drive mode it peaks at 35, in #1 mileage mode it peaks at 25, I am still checking to see if the waste gate is operating correctly. Chefgeorge
