Do I need a tune after cam swap?
Do I need a tune after cam swap? After your new cam is installed, you will need a custom tune to ensure your vehicle is calibrated for your new parts. A cam designed for High-RPM naturally aspirated power will work well with Nitrous but will not be appropriate to run with a turbo down the road. Can you drive after a cam swap without tune? yeah, you can drive it. Just don't rip on it too much, and you may stall here and there. Is camming a car bad? An aftermarket cam will more than likely 'not' increase gas mileage....
