I do use the iridiums Rev...that could be the difference. Next time I'm stuffing around I'll try some coppers @ 1.1 and see.
Engine pulled 274kw when fresh, I'd like to try another 100hp and see how I go, but those extra hp will be costly
I understand exactly your methodology, but as I said I don't like to go about it that way if at all possible..If it can't be done in timing/tune, then yeah sure no problems. My ute, 289 windsor I run gapped down plugs to avoid pinging on u/l, because the mechanical dizzy won't allow enough advance to get her running right, when I change that over to a remapped electronic setup it'll be gapped to normal again. As it should be.
I know I do seem a tad pedantic on this shit..sorry and in no way am i saying the way you do yours is wrong, because I know it works fine that way also, I just prefer the other method.
p.s
8 is a lucky number
