Spark plug and/or thermostat change before tune?

[ToddEdge]

Those of you with remote tunes, did you change to cooler plugs and thermostat?

I have been reading and found one post mentioning a 180 degree thermostat and NGK plugs as being needed to take advantage of the tune.

Curious what others have done.

Thanks,
Todd

Don't change thermostat, no need.
As far as cooler plugs, yea its a good idea.
These engines knock their asses off with factory plugs while trying to push timing for power.

Me and my tuner (builder) NGK TR6 in every LS based engine and daily driver we build and tune. Helps stop the knock.

No need for a lower thermo: http://www.tahoeyukonforum.com/forum/showthread.php?t=49584

As for plugs, NGKs are good, I ran the TR55s, but really unless you have a huge build going and are going to be pushing a lot of power, don't need to go overboard with them.
