With my bullydog downloader on the 90 hp setting and my TST on 4/4 or 4/ anything or 5/4 setting. At around 2800 to 2900 I hear a poping sound like its coming from the intake manifold. It only does this at WOT and with bullydog tow or performance setting and tst at 4/anything 5/anything.
It really sounds like something is popping back though intake. EGT's are in the low 1000's and boost is around 40 to 45 psi.
Any clues?
