My bro in law has 2002 gtp.
Mods:Cai,1.9's RR,x-haust work, stock pulley.
Is he able to run colder plugs yet?
Autolites maybe?
He will be scaning soon with hp tuner.
 


He shouldnt have any problems doing that. Once he gets the HP tuner he can check for KR and if there is none, drop to one range colder plug and perhaps see if he can drop down to a 3.4 pulley. I definitely recommend the Autolite plugs, I think it would be 605's that are one range colder.

What is the gap 55-60?
 


Actually 605's are stock. So the next step down would be 104's. But remember you always want to run the hottest plug you can without KR.As scotty said I would also recomend autolites.
 
I believe 606's are stock, 605's one range colder, then you go to the 104's if I remember correctly. In fact Im just about 100% 606's are stock plugs.
 
Ya know what...You're right...(imagine that lol) For some reason 606's werent registering.
