i do understand just trying to learn this side of things, i have previously owned a 86 charger shelby (turbo) , 94 mustang gt all motor, and i just recently sold my 05 srt-4 that i built all on my own basically but the only thing i have ever dealt with was turboes, now basically i am learning the side to supercharging. I am trying to figure out a easy way to boost it with a charger. Thats what i was thinking that the stock ecu would not be ok, just got out of your posts that it would, so i would opt for a piggy back unit, but what are the differences in price and quality, which one would i be best off with, i would say a engine management system.
