The Trinity issues were with my '07 MSRT8, and they were just enough to sour me on the Trinity now that I'm looking for a tuner for my '10 GCSRT8(the Magnum's tucked away for the winter).
I appreciate the thought that I could have reached out for help but when two of us, the other being far more comfortable with this type of equipment(I'm an old, set the jets and timing type of guy), couldn't get it to communicate with the car I felt that I was dealing with a faulty product, but when we got it to work flawlessly on a non-SRT8, I felt that there was something more fundamental going on. I don't have a lot of time or patience for this so showed it the door.
But now that I want to improve the performance of the GCSRT8, the first thing that I thought of was a tuner. And the decision remains, DiabloSport or Bully Dog? I'm in no rush, but I do appreciate everyone's input.
If you don't have patience for this stuff, you might want to leave it stock then. Anytime you add aftermarket products, there is a chance that things wont go perfectly. There hasn't been a single thing I've done to my Jeep that went without some sort of issue.....whether it be right away, or down the road. Thats the nature of this game. You have to be willing to work through the problems, and the downtime.
I have a Trinity, and for the most part it works well....as long as you don't leave it plugged in while the truck is sitting for long periods of time.....or it drains the battery. I did have it reset on me one day, and flash my factory tune back in when I tried to adjust fuel. I had a custom cam at the time, and it didn't run too well on the stock tune....but I made it home.
Bully Dog specializes in diesel performance, so I doubt they have extensive experience tuning gas vehicles, let alone a Jeep SRT8. I wouldn't even consider it an option.
