Are people happy with their Extrude Hone of intake tracts. Would you do it again?

I don't mind spending the money even for a 2 Hp gain, but I don't want to mod a new LIM and UIM set up and find that I lost a chunk of torque somewhere in my powerband and then need to go out a buy another Xcessive LIM and JDM UIM. Wasting time and 2000 just to get back to where I am.

I won't be too helpful with this topic but I don't know that anyone on this board has done an extrude hone.

Howard Coleman mentioned that he had his manifolds ported and Pettit now offers a porting service for the intake manifolds as well. Figured I'd mention that in case there isn't any other input to be had.

I'm sorry but can someone explain to me what an extrude hone is?

I did it years ago, in conjunction with other mods so I couldn't isolate the effect. I don't think it was worth it. The passages are smooth as silk, though.
