likely no. stepping up one step colder from stock or switching to a resistor type plug with the same rating will likely not yield any major difference to tune out (unless your old plugs were in realllll bad shape!)

 

the plugs are brand new. have less that 500 miles on them as of now and had about 50 miles on them when they were tuned. they are one step colder. just wrong plugs apparently.

Im ordering new plugs today (NGK 2668) and well see if that helps anything out

 

Well the plugs made all the difference in the world. No more immobilizer issues and the car has not had one hickup. NGK 2668 did the trick. and yes "R" stands for "Racing" not resistor

 

awesome news. hopefully mine fix my issues as well. now i just need to figure out how to tune my tru boost lol

 

stuff like this really helps out other people thanks for posting
