Bullydog Has Its Problems With The 6.7

[Ram3500Dually]

First off, the power is UNBELIEVABLE! Will this truck run low 14's? Without a doubt. Will it run high 13's? More than likely. At 40 MPH you can crank it up and break the tires loose and almost put it completely sideways.
Now for the bad news. Its not perfected yet. After a full throttle run it surges big time down at idle. You have to put it in neutral and run it about 2 grand for 30 seconds for it to clear up. It surges running down the road and then throws the ETC light on and it runs even worse. We let it go 7 times and the cat full light came on. It went into regen and then I had to drive it for 20 minutes before it went down to under 40% full. I had my service manager with me all this time and we had the StarScan machine on the truck to see what was happening. 47 pounds of boost!!!!! We think we know where the problem is and I am waiting for the head tech at Bullydog to call me back to talk to him about it.
All I can say is when they get this perfected its going to ROCK! As of right now I have the stock tune back in it.

Just got off the phone with the chief tech officer. The head engineer is supposed to call me back within 20 minutes.

Man. They should be paying you as a "test vehicle".

I agree but it would be nice to put the performance tune in once in a while, like say on a Friday night, and go blow off some imports

Are you sure it's six? Got to remember the Cab and Chassis also get it's own flash. The code numbers will increment but it doesn't mean it's for your truck.

I don't really know but I can tell you this, when they uploaded to my truck it was one of 5, two of five and so on so I actually got 5 updates from the D to the G

Actually that's not quite right. There are 5 blocks of programming that it goes through in an update with the 6.7, every update. I think the 5.9's had 4 blocks of programming during flash updates.
