ok so i put the stock one back in and i am still throwing the code. it is happening around 55 ish mph it never stumbles or anything just pops the code. i can get on it wot 1st through 4th gears with no code throw it into 5th and about 1/2 throttle it will ding and voi-la we have a p0087. there is no visible leakage in the engine bay i am going to update the h&s maybe there could be something in the tuning?

Try the update and talk to H&S about the update. As much as I hate to say it, it could also be the CP3 (or any of the parts involved like the FCA) trying to take a dump which would cause the rail pressure to be lower than it should be. I hope its the tuning although I've never had it happen if not I hope its the FCA because its a cheap and easy fix anyhow good luck and keep us posted

ok so h&s couldnt offer me any help. they said i shouldnt have installed the fuel rail plug and that might have caused the problem they said bring it to the dealer.so i scheduled an appointment for monday. today my backup camera started coming on intermittently while driving. and my reverse lights look like strobes! i am going to un delete my truck and hopefully they wont just void the warantee when i pull in! i checked for loose connections for my reverse sensor and everything seems tight hopefully it gets handled monday
