2011 Tahoe squeaking

Good time to get with Black Bear Performance for a tune which will not only get you more power but better shifting. I use their Autocal so they can email me tunes and make changes to it as I change things. You can find a used Autocal if you keep your eyes out, and the tune is around $300 with lifetime re-tunes. Before you buy a used Autocal, check with Black Bear to make sure it’s compatible. There have other options too.

So I’d like to just put back stock but seems like it costs more any delet kit requires I have it tuned there is no where around me to have it tuned

Just wait until you price those AFM lifters and the delete kit becomes real cheap.

Well I went with this setup hope it works https://www.amsracing.net/collectio...2007-2013-gm-chevrolet-5-3l-truck-suv-engines

He’ll yeah that’s a pretty good deal considering it comes with the Diablosport.

New problem getting check engine light saying misfire on cylinder 7 but we have verified it’s sparking and the ohm check out on the injector any ideas

 

[OR VietVet]

Sparking but what does the plug look like. Color of spark? Blue=good, orange=bad. Check for vacuum leaks near that cylinder.
