i had to unplug the cold start injector and finaly got it to run but the idle has to be set at 1300 and still isnt smoth havent driven car but runs strong when given throtle. is the poor idle due to the large engine and outher parts wile still running the stock chip? any ideas how to improve this for the time being should i put the stock injectors in and see what happens. i am ordering everything from moates to emulate log and burn but it will be a while. plans are new heads nitrious pos twin turbo. any feed back appreciated. cs nx262H-13 cam specs
