Hello, i've been reading a lot and i have heard that performance chips dont change the fuel efficiency too greatly and sometimes they even improve it by an un-noticeable hair, however I just installed my chip this afternoon and during a short 3 mile drive i got to watch my gas needle drop quite a bit. I've never seen this happen even during hard driving. Is this normal? Is it just eating gas while its adjusting to the new chip?

Thanks much!!
