I searched but cant exaclty find what im looking for......All my gears spike at 21-22 and hold at about 19-20..but my 3rd gear will spike at 21-22 and taper at like 18 and gradually drop to about 17 at like 6-7 RPMS...whats up with that?? it makes no sense all other gears dont do it, just 3rd??? can someone explain..is that normal with our cars?

 

you have different engine loads throughout the gears. Even though I have a EBC the psi still varies in every gear.

 

so this is normal then, correct?
