So I've had my stage 2 BTR tune for about two weeks now and I'm getting a really strange throttle issue, well I believe it to be a throttle issue. Occasionally while accelerating in any gear the engine will start to stutter and no matter the throttle input the car won't move. This has happened in first gear too and the car basically dies and I have to throw it in neutral for 10-15 seconds before I can drive it again. Also this happens during cruising as well so I can't even maintain a constant speed. This is extremely frustrating and BTR won't respond to my emails.
