Ok, maybe this has been asked, I did try to search for it but only found modded levels. What is the stock boost level on the 04.5 - 05 LLY, 20#?

actually I think it's about 17-18psi bone stock.. a programmer like Edge takes it to 24 and some other ones take it to 32 max, after that..boom.

Found out that mine will not go above 35.....Went Boom at 35lbs on I-15 Leaving Los Vegas, Sucks when the clamp falls off...

Thank you, just what I was looking for, so much beyond 35psi is bad ju-ju........

According to the stock calibration tables it's about 18psi at sea level.

According to my Attitude I have had slightly above 28PSI only on level 1/3, and 24 on 0/0(stock). Apparently 0 is not actually stock though.

I've seen mine go as high as 26, but that's with EFILive modded tune.

I'm not quite 100% sure how the Attitude calculates the boost but I'm pretty sure it takes the boos reading from the boost sensor which I don't beleive takes into account the baro reading.

I've seen mine go as high as 40psi with a stock turbo:eek:

Saw 26 on my edge today, on setting 3/5, strange it had never been that high and it was 110+ degrees out today...I would have thought it would be lower with the higher ambient temps.

The BS will definately help. I used it on mine when I had the edge and loved it.

I just installed my boost gauge and took it for a spin. Stock tuning it peaked at 23. Egr blocked , no cat and flo through muffler. All that is supposed to help a little but just figured this is good info on a somewhat stock setup.

Is that on a gauge or an attitude monitor? My Edge doesn't get that high on 4/5, on 0 it see's about 18

Boost guage is more accurate than the Edge monitor boost reading.
