Is the general consensus that these add on boxes are not as good as a programmed tune? I really like the idea of being able to add and then remove before servicing etc.
racechip added to list.
It seems that currently only add on boxes are available, but after seeing dyno results from a board member who got the Hartge tune, I don't believe any of the promised numbers anymore, especially above 360 HP.

I think Sportec is honest. They get you to 355 HP with stage 1 tune. If you want more, you'll need stage 2 exhaust/intake/intercooler/... tuning.
This 355 HP was also the dyno result of the Hartge tune.
