So kwik, TSI I gotta say I had an SS automatic with a 150 shot, a power programmer (for shift points, couldn't tune and spray would go boom) and a 12 bolt with 3.73's the car was raw. I think it would be a great swap. But my point is, I love NOS and wanna go ahead and spray the crossfire. But I am concerned with the traction control and whether or not you changed to a colder plug. I went with NGK TR6's in my SS, it killed performance when I was not spraying but it was worth it get in touch. I am in tight with the dealership and as long as I did not grenade the car it will keep its warranty.
