I'm looking at buying software for doing tunes. i would like to do all GM cars and trucks. What are the Pro's and Con's of both Tuner CATS and the L series of software?

I know i can buy tuner CATS direct from their website but what about the L's?

Money is not an issue, i would like to have the ability to make changes to every parameter but yet keep it user friendly and have good backend support.

Any all-in-one kits that include cables, adapters etc would be great.

Thanks!

 

anyone have any comments?? Any help would be great!
