I attached my diffuser without any trouble. Preparation is key as you have to clean the area and rub it down with alcohol before attaching the diffuser with 3m tape. I've had my diffuser on for 6 months without any problem. There is no gap as I had used my jack stands with covers to apply pressure to the diffuser for a few hours to make sure the diffuser bonded well.
