it smoothed out the idle, makes for crisper acceleration,


I wanna try an E coil w & wo the HEI module to see which is making the most difference. What is the white "thermal paste"? It's gotta be better than the dielectric grease I was using and the small capsule that come w those modules has the white paste. I didn't have any probs but I'm paranoid about (ign) breakdowns and anything I can do ahead of time to better my odds...




Not sure what the white paste is made of, all I know is it helps to transfer the heat the heat sinc, so your module won't fry. As to which component is helping the most, I think its 50/50. The module is has better capabilities, especially in higher RPM's, and the coil fires hotter, so together...KABLAM
