I had my stock NGk's in there and mashed it to feel it before I put my new 104's in. I have thhe intake and pulley. I put the new plugs in.......and it doesnt feel thhe same. I gapped them to .055. IT just feels a bit slower. It felt like I had more punch with the stock ones. should I try a different gap?? or should I go back to stock? :(

What are your mods? What were the stock plugs gapped at.

I have a thrasher intake, and a 3.4 pulley. My stock plugs were gapped at over .060 from factory.
