what kind of power could i get out of my 300 tt std if i remap chipping etc?

purely by itself, a remapped chip will do hardly anything to increase horsepower, however it is a vital requirement to have a remap or aftermarket ecu or eprom installed when increasing boost so that the ECU knows how much fuel to provide for the higher boost levels.

unlike a more modern turbocharged engine the ecu does not really control boost pressure, but as said its needed really if you are going to up the boost which costs almost nothing
