Great question. I think if you are considering porting the snout, getting a tune should be on the list of things to do as well. If you are worried about warranty, then get a 2nd PCM and have it unlocked and use for your tunes. This way you can revert back to stock and reinstall the original locked PCM.Are there any mods that don't require a tune?
So far all I have found is the incognito pulley. But I'm wondering if a set of ARH headers will free up any power with out a tune?
And ported snouts etc?
I am currently running the 3.17 no tune and no issues.I think the 3.17 upper pulley is advertised as a non tune upgrade. The computer can compensate to an extent.
Is the 7.50 reference to 1/8 mile time?Until a certain point (for me it’s around 7.5 seconds) the louder it is the slower it ‘feels’
Once ya break 7.50 you will be too busy trying not to crash to care how loud it is
Are you having any issues? whats your elevation? and did you notice power increase? I was thinking of doing it alsoI am currently running the 3.17 no tune and no issues.
I have had zero issues with this pulley in over a year now. Granted I don't drive it daily and have not put a lot of miles on it either. I moved a few months ago and am currently at 936 feet above sea level, prior was only 9 feet above. Honestly I cannot tell a difference in it over stock. Not saying there were not gains, but I did not dyno it before and after, so I am not sure overall. This is why I am now gathering parts for a build.Are you having any issues? whats your elevation? and did you notice power increase? I was thinking of doing it also
