The RPMs for example will be around 3.5k in 4th, then if I slightly let off the throttle it just dips to 2k and under as if I was holding in a clutch on a manual car rather than gradually descend as it would or should normally. That happens in almost every gear. This is my first mod. Is what I'm feeling the loss of low end torque or maybe some other issue my car maybe having with the gears and holding low RPMs? The car is 2013 2,000 miles on it.
