I installed the MM3 tuner with Anarchy tunes and a 4" straight pipe exhaust about 1 month ago. And everything has been great for that month. Recently I decided to totally delete the EGR cooler and the throttle valve and now my truck won't start. It turns over but wont fire up.

In an attempt to diagnose the problem I returned the truck back to the stock tune file. It will start and run on the stock file but when I reload the Anarchy tune file it will not start.

I have double and triple checked my the MAP sensor and it's plugged in. Anarchy has sent me a new tune but I'm still having the same problem and they are saying it's not the tune, something else is wrong.

I really think it's a problem with the Anarchy tune since it will run on the stock file but not the Anarchy tune.

Am I missing something? Any help would be appreciated.
