q-trim gain @137 mph?

[bird]

would i see any gains from going to a q-trim from my present p-trim. the times in my signature were with a p-trim 70mm 4 bolt on center 81 ar turbo with the small 6 bolt compressor cover. i know this is old technology and old news for that matter but i know some guys that have gained nothing and actually lost hp when switchting to q-trim. i find it hard to believe that my combo is capable of making more power. any opinions? or better yet any real world testing? my basic combo is stock block, 210/210 roller, unported gn1's, fast b2b, 3600lbs. mph was at 30 psi boost.
should i spend the money on a q-trim turbo???
