super88 Posted March 21, 2013 Report Share Posted March 21, 2013 I had the vette servo installed awhile back and I just put on the NGK TR6s and when it was tuned it was when I had the 17s on, because I have the 20s on now. You all think I should get my truck re tuned? Quote Link to comment Share on other sites More sharing options...
Tyson1972 Posted March 21, 2013 Report Share Posted March 21, 2013 Yes diffently. Why did you go with the TR6 plug, are you boosted or are you spraying it??? Quote Link to comment Share on other sites More sharing options...

The_aSSet Posted March 21, 2013 Report Share Posted March 21, 2013 If its a free retune sure. If you're gonna do more stuff, I'd hold off Quote Link to comment Share on other sites More sharing options...
Tyson1972 Posted March 21, 2013 Report Share Posted March 21, 2013 I use TR5's and they work great, the TR6's are more for boosted and nitrous motors. Quote Link to comment Share on other sites More sharing options...

chpspecial Posted March 22, 2013 Report Share Posted March 22, 2013 IF your speedometer is off, retune, if not, let it ride Quote Link to comment Share on other sites More sharing options...

kelleyperformance Posted March 22, 2013 Report Share Posted March 22, 2013 IF your speedometer is off, retune, if not, let it ride yeah those two mods do not require any PCM changes, they will not affect your tune at all. if the speedo is off like said above, thats the only reason youd need another tune. and yes the TR6 plugs are very very popular in boosted LS motors, they work great and are cheap as hell. just need to be replaced more often being copper, like every 20k or so Quote Link to comment Share on other sites More sharing options...
