for that drive pressure you should be making alot more boost IMHO
I agree 100%

If you want my honest opinion... your making way over 25 psi of boost...Well that ain't the problem then, again it goes good, I just think there is more in it. I know of 2 ways to plumb gate. I have a line off cfm to input of reg. then output to gate. on top of gate is vented to atmosphere. I believe Tad plumbs another way but I was told pressures are erratic and hard to dial in. Again hear say. Too late now but I'm going to try bypassing regulator by closing down line from reg. to wastegate. and see if I can get boost to go up. I'll just be careful with the EP.
Then why do tuner only trucks tend to make more power than trucks that are gated with just a tune? I don't know enough about this stuff to say for sure, but the trends point to stock trucks with stock turbos and no gate making more power than the same setup without a gate.
I am still learning all of this as well. It's hard for me to see it though. All gated trucks that have been on Dunbar's dyno do lower than not gated trucks with the same setup. That is all.
Are you looking for readings from another gated truck, or a non gated truck?
I was seeing 45-48 without a gate. Unsure of EP at the time. Now with the gate I can barely crack 40 psi with EP at 70-75. But I am still in the middle of playing with it.
so your reading absolute pressure on both boost and back pressure, easier at a glance to see how close to a 1:1 ratio you are
That is actually a good idea that I didn't think about. Beats doing all the math. LOL

So what is the point of the PCM reading the MAP sensor when it maxes out before stock boost levels are reached?
