Just installed a Turbo into my 89 rex si, put 450cc injectors and picked up a chiped ECU. When i first put the turbo in everything worked fine. Iremoved it, and just recently installed it again. This time when i installed the turbo an ecu, started the car and it immediately reved up to 3500rpm. Has the Ecu gone bad, or have i missed a vac. line or something?? need help asap
