yeah, presto_z, i put one on my LM1 and noticed alittle top end improvement. most would recommend against putting one on a LM but i say since its a manual cut-out, its about the cheapest hp u can buy!!

If you dyno'ed and got those numbers on a diff day, then its def not apples to apples comparison.
