Hi guys. I'm using e-manage for my car. Last week i've tuned my car. Let say i want to change my gain(boost response) and peak gain(stabilizing boost) setting, do i need to retune my car?
Have recently seen quite a number of 350Z with super charger for sale. Have no experience in VQ before and was wondering is it a good idea to do so provided that supercharging kit from HKS or others.
