Have 2013 RAM; I had it deleted a little over a year ago.

When I first got it done, it had a bad lope when driving at lower RPMs using an EFI Live tuner with an 80 horse tune.

I took it back to the guy who installed it; he said he had EFI Live and sent him a new tune.

After he installed he said it was shifting very hard, so he supposedly installed a Bully Dog tune and told me to come to get it.

So now, my exhaust brake hasn't worked since, and my push-button start also doesn't work now.

The lope is gone and seems to run Ok.

I am so wondering if a new tuner would fix my issues?

And at this point, the ECM is Vin locked.

Any advice would be great
