Hey guys, do you think that a basic ECU chip Squadra etc, would warrant the need for a slightly colder plug, gived that advance is significantly changed? (plus the fact that the act of installing a new chip shows intention to drive like you stole it). I'm thinking generally, but with reference specifically to my 8 valve twinspark.

Hi,
I had an article on this by which I can't find anymore but I think it recommended coolerplug changes in step ranges of about 50bhp. I would definitely for an upgraded plug type - I use iridium plugs
