[QUOTE="JPs2013GT500, post: 15341449, member: 156952"] Thanks for the feedback. Kudos for making it through my wall of text. :rockon: Great ideas, very much appreciated. I'm scheduled to have headers installed next week but I think I'll change that to have them run a compression test & diagnosis session instead. Side note: This morning I removed the super snake axle back and put the stock mufflers back on. I did so because this puts the car back to the exact configuration when it was tuned last year. It runs great again. Not sure if that will change again tonight like it did with the thermostat swap, but I'll see this evening. If it doesn't change and runs as well as it does right now, then it would seem as though my engine is hyper sensitive to the slightest changes. I wouldn't have expected to have the tune updated for a simple axle-back swap. [/QUOTE]
