I know my HPOP is weak, only holding about 1500psi at WOT, but I'm wondering why I don't get a code for it. I have gotten the 1211 code only a couple times in the 2 years I've owned the truck. It just got me wondering if I have something not reading correctly to set the code. Is the ICP sensor what the PCM uses to set a code or not set a code? Do most tuners make it so that the code is not set? I thought I saw it on DP tunes that it wouldn't set the code, but wasn't sure about others.

dp has a no code tune. It raises the threshold before setting a code as I understand it. That's what I have. Maybe someone with more knowledge than I will jump in. If you do need a pump, I just put an Adrenaline on my E99 and what a difference it made. I love it. Good luck.

Yeah I do need a new pump and it is on the list of stuff to do, this was more of the I was sitting here bored thinking of stuff questions I had, and also to make sure I'm not missing something that is causing me to not have a code.
