Question for Underdog Performance

[Eric Pennal]

I just bought a Screamin' Demon coil pack from your web site.



I already have an XCal-1 (with two performance tunes) that I bought from Wayne Foy, back when Wayne was cool.



Do I need to get my tunes updated to take advantage of the new coil pack?



Thanks.

No.

Todd got it. You do need to regap the plugs to take advantage of the screamin demon.





It will ship out Tuesday Eric. Thanks for the business.

Thanks guys.



I do plan to re-gap the plugs. Now, if only I can find a spark plug gapping tool that goes as high as .065".
