Got Trinity from Sean at Hemifever. Loaded his 93 octane tune (already have 93 in tank - it's all I run). OMG what a difference! It is a night and day difference between the 93 Bully Dog tune and his 93 tune. I knew it would be a difference, but I am really surprised at how big of a difference it is. Throttle response, power, everything. Even feels like it shifts a little better. May be my mind on that though. I will keep the BD because I like the gauge part better than the Trinity, but I will never have a hemi again that doesn't have one of his tunes. I'd have to say it's probably more than twice what the BD puts out. No lie....

Congrats HLram on the purchase of your trinity.

HLram do you keep track of your mileage at all? I am curious what/if any changes you notice in your fuel mileage with the new tune.

Its really good to see this post especially considering that I ordered mine from him over the weekend ($575.00 labor day sale w/ custom tune, I just couldn't resist). I cant wait and I'm glad to hear its awesome.

I drive from east texas to south texas and back a couple times a month so I have a very good idea of the mileage. I bet it will get better mpg if I can keep my foot out of it bc the throttle response is alot better. It feels like it is taking smaller throttle inputs to get to speed etc. I will update when I go back down south in a few days.

This is the kind of stuff I wish I had seen before I ordered my BD months ago. Its not that I dont like it, its just if the gains are that much better the extra couple hundred sounds worth it. Im waiting until I do some more things to my truck to make the switch to really tie things together but theres no doubt as I get a few more mods Ill be ditching the BD. Congrats on the new tune!
