like title says after i tuned my car on a dyno and wasnt too happy with the midrange power, i switched the mrrh to a bcrh expecting to feel a fatter powerband. after the install the car did feel a tad bit mroe tq but lost power in the midrange and top end. and also when i hit vtec i can hear some kind of air leaks under passenger side. im guessing i may A) have a header gasket leak that causes my car to feel slower or B) needs a retune ASAP. what u guys think?

 

your car is tuned for the other header not the buddyclub. also who tuned your car and how does the dyno graph look and how much HP did you put down

 

retune and definitely check for any leaks
