up to 6ms on ls1 coils.


On bosch coils wouldnt be going over 4.5ms. And it would not be because of the coils. it would be because of the x4 box.

4.75 I am at the edge,
I gained few hp up top from 4.5ms should I go back or stay where I am at?

I can crank it up to?
and then drop it back down before I leave the track
