I changed a TM7 intake with a 950HP carb. to a M1 4500 intake with a 1050 Dominator at the track and the car pick up .15 ET and 3 MPH with no tuning changes. That combo went .3 and 4 mph better with tuning., squirters help when they are the right size I have changed 1050 Dominators at the track from a 9375 with all stock jets and squirters to a 8896 with stock stuff and saw a .13 loss and 1/4 mph loss, switch back and the ET and MPH came back
