I have a project I have been working on. Its a 2010 Grand Cherokee that I replaced the 5.7 and 5 speed transmission with a 6.4 and 8hp70. I am using the stock 5.7 PCM to run the 6.4. I paid a shop to modify my 5.7 tune to run the 6.4. unfortunately for me the shop decided to go out of business 2 weeks after I paid and got my tune. The engine seems to be running funny and I was wondering if someone can look over the tune file and see if something is wrong..... don't want to blow up this 6.4 with a bad tune before I can finish the Jeep.
