As everyone else is saying, if your going to spend that type of money get a programer.
I'm running the Superchips Flaspaq along with an extra ground for the TB. The Flashpaq does come with in the tunes programming to reduce throttle delay.
I read somewhere, I believe on this fourm about grounding the TB helps with reducing delay. I did it about a year now and have not had an reason to undo it.
Also the Flashpaq has Trans programming (Paid Option $100 on top of the Flashpaq)
