I think they will be quicker in ET but not faster. At least at first they won't be if ever. You would be surprised at the Pro Stock teams that have already been testing EFI for several years and even trying to get NHRA to allow it.
NHRA will not allow it is the only reason you do not see it yet. It is called *Sponsorship Big Bucks still dictate the direction the rules go*. That is the only reason why the very popular Pro Stock Trucks were abandoned.
