I havent a clue when it comes to spark plugs i'm getting some some pretty bad hesitation on boost so i'm gonna start with plugs replacement being the cheapest (they havent been replaced for 50k). I've read about hotter & colder plugs in some posts going back a few years (2007) i imagine now there are newer plugs about. My current tune is a jabba stage 2 map probably making anything between 260-280.
Thanks in adavance
