Those are awesome numbers! Great job. I might get there with a tune. I only have the single CAI and 62mm pulley but pulled in fourth gear 350hp and 342 torque at 5800rpm. In a third gear pull I had 410lbs of torque. This was on a mustang dynonameter. They tend to be lower than a dyno jet by around 12%. I also had washed out spark plugs. Replaced them yesterday. I had to do my headliner too.

Thanks for the post. Good stuff!
