Not on these, too early.
The older similar Sho Shop LIMs did have dyno gains posted somewhere in the old forums, I think it was 5-10hp.
Would complement a honed UIM, CAI, exhaust to make a hot 2.5.

Got the big bore installed. No "official" dyno numbers, but definitely a noticeable increase in the TQ curve. It pulls hard(er)! I have a catch can routed into my PCV system so my UIM/LIM had very little fouling. In short, the cleaning of the IM's played little if any into the increase in TQ.
