Boost psi

[lamb3903]

Is it normal when my boost 1-4 gear is 27-30 psi range then when it shifts to 5th it drops down to about 20 psi ? I have a sct running spartans aggressive street

My boost has never been over 20psi. I run Matt's (GearheadAutpPerf) SRL and never see more than 10psi during normal (55-65mph) driving.

That's right...before the SCT tunes and even now...I've never seen more than 20psi. Like I said, my normal range is 5-7 and up to 10 for normal driving...I haven't towed yet with Matt's TowPig. Maybe something is wrong with my CAC tube boots or Turbo??? Is it supposed to be high?

Um, I dont know.

Like mentioned before, stock my truck will hit 25lbs(maybe 28 on a highway pull). With my extreme street at highway speeds I am between 10-20lbs. It will peg my gauge at 35 pulling a hill.

mines the same as moyock.....mine never exceeds 20 even a run with it on the floor

I hit 32 with my race tune and it drops to 20 in 5th, if I am cruising 70 it can drop down between 2-3 then when you hit it it spools back up to 32.

Well under WOT on my race tunes I'm about 20psi. However if I lug it and keep it in one gear it will go up and peg my 35psi gauge. I've hit 31 a couple times with my truck on stock tuning, unloaded, going up a slight hill.

You should be seeing over 20psi on stock tuning, never heard of one below that with stock setup.

i think 25 psi is what most stock trucks make. thats what my tech said. i also hit 32psi with race tune
