Re: Tuner for 3.6 and v6 regrets. Help
Shoulda got a v8. Mileage in the hills would have been close cause the v6 is struggling whereas the v8 would have lubbed up. Also, 87 is fine. 89 gives you a couple extra ponies cause a knock sensor advances the timing a smidge I believe. Not necessary and I have never put a drop of 89 in mine with not one knock or hickup in 10000 miles. No tuners etc for anything yet. You're stuck.
