saleens so fast

The spout trick is one where there is no clear evidense about gains or losses.

Sitting still on the dyno, removing the spout seems to cost a hp or 2, but on the track it seems to have the opposite effect. The best explaination I've heard is that when sitting still on the dyno w/o the spout the engine sucks in warm air, but when going down the track, there's enough wind that the engine still gets enough cold air.

But to anwser your question, no, you should not need to reset the computer when removing the spout.
