Listers, On WOT my A pillar gauge reads 22 psi of boost for about 4 seconds or so, then the boost needle drops down, usually to about 10 psi, afterwhich I lift off throttle because i've reached redline. Changing to the next higher gear nets a similar result. I've got an MTM chip Stage 1? (from Previous owner). What gives? -m 95.6 S6 Avant
