I'm not sure offhand. I do know that a Bosch (or whomever) brainbox could easily run $1,200-$1,500 for the box alone. Then you add the cost of reprogramming it. Fill out a parts request form on PartsShop and we will be able to tell you exactly. I would not say for certain he is exaggerating, but ask about satisfaction warranties. Then find a dyno near your house. Figure a 20% loss of HP's in the drivetrain and calculate if his software is "as advertised". If they do a non emission legal brainbox it may trip some engine codes. Talk to them about that ahead of time and see if they have a way around all the emission police. (for track use only of course...)

Hope this helps...Lee
