I recently got my truck dyno tuned and I am not happy with it. But the people who did it are no longer in business. Can some please answer my question. Can I load a canned tune on to my truck after having it dyno tuned?
i have a 2018 silverado 1500 with the 5.3 and speed engineering LT headers and at a higher rpm or between 80-85 i can feel my headers touching and vibrating on my frame. has anyone else had this issue? i read one forum where if you replace the motor mounts the problem is fixed
