Is there a post on dyno results of various mods and custom tunes for the 5.4?
Just looking for the info to pass on when friends that are thinking about going with a tuner, and the advantages of a custom tune from
PHP.
I have just got my custom tunes for my CTS and i am going on a trip tonight towing a 1800 lb atv trailer to Whiskey Springs Atv Trail system.
I have a custom 87 performance and 87 tow. Stock truck no mods, soon i will be doing the gotts mod and later on i will ber doing a cat back and maybe a few others.
