I am using .60 now as this is what my tuner recommended, previous was .75, 60lb siemens injectors also. Idle quality is quite good which was a concern of mine and not because of the gap but the injector size but I am very happy indeed.

My power is only around the 330rwkw on my BA but boost is near 19psi and zero missfiring etc.

Friends (ray076) FG is 18-19psi running .60 gap, same injectors and making 390 something with no missfire either.

If I was running close to 15psi and up I'd go the .60 gap. Just my opinion now though after using it.

im running 20 psi on mine gaps are set to .5 anything above that and they kept blowing out when boost got up or overboost and idle is fine... in saying that a colder conventional type plug does work better and produces better spark when chasing numbers rather than iridiums ... as funny as this sounds its true and u might make more power aswelll obviously they dont last as long but hey the are cheaper ... ill get the ngk derivative part number if anyone is interested and you can ask your tuners about it aswell

I use a VL Turbo plugs and gap them to .6. I have tested the over priced iridium plugs on my mates dyno and they make no difference in power compared to the $20 a set VL Turbo NGKs. The only difference is they dont last as long. On 17psi I was changing my iridiums every 30000km anywayz.

Ford at Chermside Brisbane I got a set of standard ford turbo plugs for $68 or $72 and in Townsville's ford they wanted $120, cheapest they would go was $90 and I still told them to fck off.
