thats prety tits

i got dyno 2000, and 2003 and there pretty good programs.

The ls-x section lacks options though, but you can't complain too much with it being free.

cool

They all seem to lack options....good for free...but yes, I would like to "build" it around more options....as in everything they have to offer..... :)

Its funny how folks count on cams. Do you know that the famous Duntov cam only had .387 lift? The biggest mistake in engine building is installing too big of a cam.
