still havent installed the new plenium, just haven't had time. While on the topic though, anything I should expect from it under normal driving? I dont think the single blade will sound any different, and I dont think it will be anymore throttle responsive, will it? I heard I will notice it more top end... Is that true and also is it true I may lose torque? thanks, Shane

I asked in another thread when I got the intake spacer if porting the upper intake plenium would go well with it...

Shane,
Porting the upper intake plenum will actually hurt your low end unless you have a highly modded Lightning. It increases your high rpm 7-10 HP on all the ported plenums we see here. But you loose just as much on the low end. It's really your option but I like the throttle response so I leave it unported.
Hope this helps,
