just a random question here,

if let's say you had your car tuned, all works perfect, do you need to keep the quarterhorse installed into the ecu or can you remove it and still be on the current tune?

thanks

If you remove the QH then youd be running on the stock rom tune. Youd have to write it to a chip. Info is in the getting started write up.
