F1 tuning claims 30% hp increase, 40% tq increase, you believe it?

im gonna try it just to try it, cant find out 100% unless I actually do it so yea lol… And maybe they lied to me but from what they said nothing is mailed, they said they take out the ECU and work on it themselves. They said the tune should take 1 day which would leave no time for mail.

F1 gives them a boxed/cannned/pre-done/mailorder tune that they flash on the ECU. There is no work involved and no one actually tunes YOUR car.
