Surging, almost stalling, sounds like mine was more mis-scaled then yours because it would do it a lot more often then just a long ride. anytime i was on the highway for a prolonged amount of time, 15-20 min, it would do it.

Car felt sluggish and lazy. I was also running e85, met up with my tuner. Re-scaled the intake and injectors and all was good. I think my car was tuned with an intake leak or boost leak. When I found the leak and fixed it, thats when this started happening.
