I'm looking at getting some cams in the next couple of months for my car. My question is, Do I need to get cam gears even though I'm going to get tuned for them? I will be using ecuflash or I will get another dynoflash from al. Why would I need to get cam gears if i can change the timing via the ECU? I really don't want to spend the money on parts I'm not going to use. Any input is greatly appriciated.
