I am try to get him to explain what his is doing and trying to do in a clear and concise way.
Which he has not done yet.
If you look at the rom he sent over which he said is the rom he is using he has only set the timing to -10 not -20 or -40, but -10. So I don't see how he can get more than -10 degree of retard.
I am trying to get him to help himself and show us what he is actually doing not what he thinks he is doing.
It is very easy to get it wrong, and he is obviously getting it wrong and he doesn't know it. he only has the timing set to -10 degree.
Personally I don't run pops and bangs it is a pointless and some what childish thing to do.
However childishness has its place and we all like to indulge our inner child every now and then.
The rom I posted up was from a car that successfully had pops and bangs setup on there car and does pop and bang on over run. But it does depend on what exhaust is fitted. As silencer/mufflers can deaden the effect massively as we found out.
