Can anyone tell me what kind of results I can expect using the Trinity on my 3.5L Magnum ?? Auto w/ KN CAI. Pretty much stock other than that. I also have 05 GTO 6.0 that I plan on using it on as well. Can I use the same Trinity on both vehicles??

Now is this with the Performance Tune included with the Trinity or is this with a custom tune using the Trinity??

Hey I'm new to the Trinity and have not ordered one yet as I'm curious if its worth the bank. I have an 05 GTO M6 K&N CAI, X-Pipe. Other than that its pretty much stock. How much gain to you get from using the Trinity??
