I was looking at some various performance chips for the northstar. I find it had that one little chip less than $100 can add 15hp or more in some adds claim. Are these all a scam? They claim to change the fuel air ratio and change the ECM for better fuel air mixture. I am not a believer in most simple mods like this but I thought I would hear your thoughts on here. Anyone ever tried one? Let us know.
