also, due to how gearing works, acceleration at redline relative to in a higher gear should pretty much always be better.. unless your car REALLY tapers off badly.
all you have to look out for is don't hit the limiter, as the car retards and loses LOTS of power and acceleration.
our cars shouldn't be driven to redline, we lose retarded amounts of power towards the end of our RPM range. Or atleast that is how I feel with my baby.
And a JB4 would get you your PSI levers and it is very sensitive and accurate. As mentioned before.
