ok i split the turbo intake hose on my sti i have just got a brand new silicone replacement i have also bought a hks induction kit
HKS (SPF) Air Filter Induction Kit Subaru Impreza 93-96 on eBay, also, Performance Tuning Parts, Car Tuning Styling, Cars, Parts Vehicles (end time 18-Oct-08 20:02:02 BST)
i am looking for a ecu unit and controller, i have a decat coming Wednesday and am looking for a fuel pump and and new headers, and front mount,

i will fit the induction kit and de cat as soon as it arrives, but wont fit the front mount or headers, fuel pump until i have the ecu and controller,

then will go for a re map,

can any one suggest a good ecu, to go for, or any advice on this would be appreciated
i am guessing it would not be a good idea to fit front mount and headers and pump with out having re map done is this right?

also what sort of power gain could i expect from doing all the above?????
