i'm trying to figure out where this weird boost leak is coming from.. i recently did the foil delete so that makes me think it's from putting the i/c pipe back in wrong but i don't know. cruising at 40mph in high gear, in any of the tunes, my truck sits at about, maybe 1100-1200 rpm's and boost generally goes no higher than 8psi before downshifting. i'm noticing this drop in boost, and a whooshing noise from under the hood, but only when i'm at about 1100-1200 rpms and at about 3-4psi of boost and hit a load (like a small incline) and start to give it a little more pedal. with the tunes my truck can sit in those low rpm's and pull itself up the hill with the low end grunt, and it still does but feels a little less responsive and once i start giving it pedal the boost gauge goes to 0. then when my truck downshifts it goes up to whatever psi, you know, 18, 20, 26, etc. and it doesn't lose boost in the HIGHER PSI's, only in the lower ones. what gives?
