Spark and timing

[01FFF]

I just want to ask you guys. The shop installing an NX system said I don't need to retard my timing or run cooler plugs with the 100 shot. Any opinions?

If your timing is stock then you don't need to retard it. If you advanced it any with a PCM tune, then yes, I would pull that timing back out.

I highly suggest running a colder plug, like a NGK TR6.

Thanks, it is stock programming. It just sounded funny.
