    need help have a few question would love all input

    so i have a 2011 ram 3500 srw. im the third owner and it had 92 k when i got it and i DPF and egr deleted it and installed a mm3 tuner and s&b air intake. my questions are is sitting in park my trans pressure is at say 62 psi when i hit the brake it jumps to 129 psi and will stay till i hold of the brake. is this normal . at 15 psi of boost my ex pressure is at 28psi is this normal or do i have an underlieing problem and i think im getting a defueling problem while pulling and on a hard pull

    Ill have to double check my line pressure on MM3 but that sounds like it should be correct with line pressure. When applying the brake the trans is getting ready to change gears/become active so increase the line pressure for the movement desired.

    Exhaust pressure sounds correct. These truck with stock VGT turbos have about 1.5-2x pressure of boost.

    what makes you think truck is defueling? How are rail pressures?

    Does it only do it when burning out? That seems like traction control/nanny kicking on. Even with traction control off If the wheel is turned at all when tires break loose the truck will defuel by design

    Maybe someone else will chime in but I’m willing to bet it’s the ECM/stability control shutting it down. Traction control is stage one and stability control is stage two. On the 13+ If you cut the traction control off you can spin some but eventually stability control will kick on which you can’t help without pulling a fuse. One way to find out is pull your ABS fuse. If you do make sure it’s on a closed course as you are at your own risk!

    Would this still pertain to a 2011?

    My understanding is yes. ABS disabled = no traction control at all
