I have an auto too with just the free WAI... You can definitely hear and feel the engine opening up around mid 4000.02SilverSE said:In my auto with JWT Popcharger I can definitely hear
a difference in tone around 4000-4300 RPM's.
It should be the same whether u have auto or manual if
I'm not mistaken.
are you sure it's not the intake runners switching over? My bro's 93 is noticable when WOT, but not when cruising. Happens just short of 4000. His 2000 Maxima SE 5sp is less noticable...u really gotta be in tune w/the car to notice it switching over. I had a friend ask if the 93 Max had VTEC cuz it kicks damn hard right before 4000...and I usually shift around 3000.fatboy said:
