I have a 2002 Tahoe 1500 with 5.3 auto that I just use to tow my boat. Was wondering if anyone has a good tune I could look at to try to make more power for pulling my boat. Or possibly some advice on what changes to make to help with more power for towing. I have searched the repository for any aftermarket or professional tunes and all I could find was stock tunes. Thanks for any help!! My email is [email protected] if you would just like to send a good tune to get some ideas from. Thanks again
