Re: N/A with DSM 450's & chipped ECU
 

Is the chipped ecu setup to run 450's. It sounds to me like your car was turbo, but now you want to go back to NA until you get your downpipe made. Just run it like it is then. :1

I'm currently running 450's on an n/a b18b. As long as your rom is calibrated for 450's theres not an issue. And no it doesnt run rich. I get like 300 miles to the tank still
