there is a big difference between manual and electric boost controller.
most ebc will have gain setup which allow you to bring on boost early (with-in reason, the higher the gain level the more probably you will get boost spike)
there is a reason why manual is $50 and an ebc is anywhere from $250-$600.
Most of them are very simple to install they will have only 4-5wires, which will be something like : ground, power, ignition, lamination etc some many require tapping into ecu wires but it is a fairly straight forward job
