Coils

For what I remember reading a gain from the LS2 > D585's was much less than the jump from LS1 to D585's

thats interesting..... so we have 3 gains and 1 loss. Wonder y they lost power and 3 others have picked up hp. I think i may get a set since they are cheap enough and do a test on my own car. Did they say anything as to why it may have lost power. I cant understand the loss in power. I can understand no gain. But i cant see a loss with something that can generate more power. Then again im no electrician.

i have no numbers from my ls1 to 585's but there is a noticable idle improvement for example it idled great at 950rpm's and now the idle is down to 800rpm's and idles awesome and very smooth ??
