ok just pulled the blower off today as seen in my other post i need to know what the best plugs and thermostat to run with a ported eaton only mods are a 6lber and a cai
I think stock thermo is 180* I know alot of guys go with a 160*
As for tuner IMO the handhelds are better than a chip, although by asking which tuner I think you mean a Predator or SCT Excal II. I have a Predator but it seems alot of guys are going with the Excal II.
I think both are great unless you meant which dyno tuner then I dunno although Id go with Amazon.
NGK TR6's for plugs, I ran a 160 Stat because im in florida and i will never see the cold temps that you will being up north. So if I were you i wold stay with the 180. The handheld tuner should be considered by which one your tuner knows best.
