best tune for a stock ls1
im really looking for the fan to come on sooner,harder shifts,and any other small gains i could get with just a stocker. at the moment im running constant 13.4s @106. also what to expect if any?
I would say if your comfortable with a little learning curve tune yourself if not a handheld or a professional tune might be the way to go...just remember that you most likely wont be able to use that predator on your next car whereas hptuners can be used on hundreds of model year vehicles car after car

I would say check out our help file & demo section...we even have a how to demo on changing fan temps for LS1's http://www.hptuners.com/help/getting_started_demos.htm as well as a ton of other more advanced features of our software.
