hahaha.. np man...
well, if you want the MOST out of your truck, then yeah, a custom tune is the way to go...
and if you want me to do a custom tune for ya, then you don't have to make all those adjustments you're doing now - I will do 'em right in the custom tune, along with all the other tweaks I make... so all you'll have to do is send me copies of your two tune files, (original backup and last tune written), and data logs... and I'll do all the rest...
Here's info about my custom tuning:
http://www.dslogredux.com/DiabLew_Tune/there are links on there to all the info and apps you'll need - i.e. how to export/import tune files, how to do a data log correctly, and what parameters to data log, etc etc... as well as a link to a small sample of just some of the Testimonials I've received from people I've done my tunes for.
Thanks for asking!!
