Any updates?
Scheduled to take it in Wednesday for tune corrections.
Turns out it wasn't tune related. The main power wire and o2 sensor wire were cut when the guys stole my cats which I was told it was reading lean and dumping fuel due to those cut wires. It is doing better on fuel I will say but now I can tell it needs a fresh set of plugs and plug wires so diving into that next.

Glad you figured it out but a little concerning that they didn't notice that when tuning.
Good point, I'm now wondering about that myself.

Thieves suck, sorry you had to go through that.
Yikes, how could they have missed that?
Hopefully they logged and saved your factory tune file.

Tell me about it, for me that's just life take your licking and keep on going the only thing that sucked to me was I don't know who did it because I believe in an eye for an eye lol but thankfully they did have a stock file and just modified it and it's seeming to be better and is slightly better on gas. Not like it was but I could contribute some of that on the aged components needing replacement.
