This thing is awesome! It has so many tunes and calibrations for so many things I'm afraid to get to into it. On the tire ratio recalibration do I simply put in your tire size like on the tire in the same order? I did the smallest tune, 87 one because I only have a cold air and exhaust. If you blow your engine up could they track it back to the tuner? lol.

 

You are not going to damage the engine with canned tunes. Now what you need though is a good cam and some custom tuning to make the truck jump and run

 

Your truck is a BEAST!! I like! I really wouldnt mind every internal and external mod I can get on this hemi but it's just this lifetime powertrain warranty that I don't want to mess with. I've read the Magnuson Moss warranty act but never got into depth on if a cam would void it. I know cams can go flat and metal can get into your engine and with my luck it would do that and they say the cam was at fault lol.

 

If you went with a mild cam that didnt need custom tuning I dont think the dealership or shop would ever know because if they reflashed the PCM with a stock program it would still run. Mine however it is custom tuned.

 

Mines just for pulling and I like the hemi and all but its still a gas burner and not deisel. The truck does everything I need it to do and pulls everything I need it to pull. The only thing it does is when going thru hills it shifts funny, sometimes it fast and when in "Tow Haul" and on the interstate it doesnt want to shift into OD. I know most the OD problem can be solved by using the MDS again but when towing I don't want it if not on a perfect straight stretch. This tuner can help that by turning MDS off and using the "tow haul" or not using it. I never was good at computers and this is one lol but with time. Is there a option in this tuner to turn your cats O2 sensors off if I were to gut them or take them out?



I noticed all your 6.1 mods and stuff. I know it's hard to know unless you Dyno unless the trinity can do this enough to let you know. How much power torque wise do you think your mods and tuner gave that hemi?

 

And thanks a lot for the help you been super helpful! I'll just have to play with this thing and read up on their site to get the hang of what's what. I'm overall very happy with it.

 

Oh and I pull a 16ft trailer with my a fullsize regular cab truck. The trucks in the neighborhood of 4,000, not under.

 

Dont let anyone fool you, the Trinity uses the same canned tunes as the Predator. It just displays more and has a few more functions. IDK where I am at just yet. Ive got some more tweaking to do and then i will jump on a dyno to see where I am at before I pull this cam and go to another one

 

Yea, I just like the temps, and gauges the Trinity shows, that and the fact it can stay up by the pillar. Who installs your cams, a local shop?

 

There were some mods that the warranty wouldn't void if a dealer or local shops installed the parts. That verses a shade tree lol.
