i just had the AEM tune done. overall fine but the mileage is off like everyone else. on my second engine i have about 10,000 miles. Truck has about 60,000 on it. i have an extended warrenty as well. FCA was great to work with. My question is simple, will the GDE tune toast my warrenty? I am looking for a definitive answer. I would take part of my settlement the get one with all the trimmings but if thisengine blows I want to be sure THEY put in another one. although I truely believe this is a much better engine than the first one. Can anyone answer the question without guessing?
