man theres usually a price to pay with more power upgrades, other than that is there a noticeable power gain?

I had the second gen DFIS setup and its is much better than stock but
you wouldn't want to delete the trailings, they still help some.

That setup burned out ( it was the ignition box on the SA I think ) and now
I use GM HEI ignitors and Ford TFI coils (one for each leading plug). I then
removed trailing and stopped using the vacuum advance because this
setup was so much better than the 2GDFIS. Very simple, strong and easy
to source replacement parts cheap.

Unfortunately the only writeup I have is on the other forum. Do a search on
that forum using my username (its the same everywhere) and you'll see it
show up. Lots of pics and diagrams for wiring it up.

I don't want to post the direct URL here out of respect. Maybe someday
I'll have the time to reproduce some of my how to stuff on here.
