Recently bought a 2007 3.6L with 94,500 miles. The timing chain was replaced at 88,000 miles and the ECM modified. My question is- given that I do the recommended 3000 mile oil change and keeping it topped off, should I expect the new chain to last awhile? Did they make the replacement chains stronger or are those questions that are unclear? Thanks in advance to anyone with reasonable experience that takes the time to help clarify my concerns.
