I am looking into getting a screamin Demon coil pack, what improvements have anyone noticed, is it worth it and will it make a bigger difference with an X-Cal 2 tuner?

 

A few guys have done a review on this..just search screamon demon coil pack and Im sure it will come up...as far as bigger difference with the xcal 2 I dont think the xcal 2 will effect the results of the coil pack but the xcal 2 IS the best mod you can do..IMO of course

If your plug wires and plugs are in good shape, and you aren't getting a CEL with a misfire code, you will be throwing your money away! And the Ford EDIS coilpack is way more reliable than the aftermarket coilpacks!!

 

OH lord here we go...
