Not yet, but he is planning on testing that also. But regardless, as tested out of the junkyard with nothing more than headers, it allready makes more power than that pos UTG 318 we all hear about
LOL! I believe it it looks like Holdener knows what he's doing. Imagine if Holdener flips pistons,and does not come up with a measurable gain,what will UTG fans say then? I predict they will say Holdner "did it wrong"...:)
