I am seeing 34 psi max with Erics tunes. Was a little reluctant at first, but with heads, studs, gaskets, fuel system, I am not scared any more. What fun it is.

I saw 35 psi today running stock so I backed out of it. It was an eye opening experience, usually this type of boost is due to running a tune. ???

You guys have to keep in mind your digital gauges might not be too accurate. Chips lie to the computer so it'll read low boost, the same reading that some of the chips display on the monitor. Just because it says you only have 24 psi doesn't mean that's all it's pushing. I drove a dodge the other day with the edge juice w/attitude display and a mechanical boost gauge. they read the same up to mid 20's then the Edge didn't go higher, but the mechanical read up to 44psi. Just keep in mind a good mechanical boost gauge, or stand-alone gauge is much more reilable than the one reading manipulated info from the chip...

Mines mechanical also. I had one that went 0-35, but I started pegging it after the sct, so now I have one that reads 0-60.

I wonder why all you guys boost so much more than me? I have requested and asked my SCT custom tuners to add more boost, but they reply it is already maxed out.

I know that if you are still running EGR than you typically see more boost. But most SCT tunes disable the EGR.

Comments?

Thanks.

From my thinking, that's a lot different from disabling it... My truck is run daily with the Aggressive Street Economy 130 HP tune, and it'll make 34 PSI, EGR not factored out.

Or sticking turbo veins. It's been my experience over and over that anything over 32-34 with a stock turbo is totally useless. You actually start losing power and gaining EGT's because the turbo "chokes" and doesn't move the air...it's simply backing up so to speak.
