I have a 1986 GN. When i got it was stock. I have changed the chip and injectors with ones from Turbo Twitte. I just put in a new stage 1 transmission from Extreme Automatic. I have changed the coil pack and the tires. When I got this car it would turn the tires from a stand still and when the turbo kicked in at 30 to 40 MPH. Now it will not turn them at all. What have I done wrong. What do I need to go back and change. Could it be the transmission? Please help.
