Installed the accufab to my 98 Vortech Cobra, set the throttle position sensor and all is good. However my car was custom tuned using the stock Ford throttle body and wondering if I should get the car retuned for the Accufab? I assume a little more air is getting into the engine, not to mention the meth injection as well. Not looking to run lean. However the MAF I assume is reading the amount of air and telling the computer to adjust fuel amount...making a retune unnecessary? Thoughts on this, is it safe without a retune? Thanks in advance.
