i think you have to have a new computer because of the fact of back presher

You can do it very easily . Take it all off EGR/ smog pump / canister solenoids / everything that hs to do with it . Make cover plates to block off egr hole . Fordfuelinjection.com sells the resistors to solder into the plugs where the EVAP solenoids were and a plug with the correct resistance values for the EGR to trick the computer into thinking all is well with the emissions system . I did it to my 89 5.8 bronco with C6 and it works great . Only time you have to change the computer is when changing trannies or motor size . You can use a C6 with an AOD computer but the timing curves are a bit different it will work but not as good as it could .
