man they're kinda pricy buggers and I understand with our ethonol content that they definately get more abuse than they should.
I'm wondering also if its just the PCM getting used to the new tune?
Running canned 87 - running 91, the code pops up every so often... I'll clear it and then its back under high throttle conditions.
Running canned 91 - running 91, the code popped up again, but has since self cleared and I've ran it for 3 days, even pulling the boat without the code.
I was really close to getting the shop to replace it... but maybe its just a re-learning? but that said if I did one side, it probably would require the other.
Also... I know there are tons of other custom tunes, but I am really surprised how good the 91 canned tune is. I have a Full Race intake and just a cat-back AFE exhaust, and wow... this is completely different truck.
Thing is... is a canned tune "safer" to run than a custom, or is it vicey versa? My truck has 172K now, and its been rock solid, so hoping even with a 91 or 87 tune, I won't overly compromise the reliability.
That said, my fuel eco is impressive... I dropped from an avg. of 13.1 down to about 11.8 - hoping its not running the motor too lean
