Ok I have the dreaded locked 07/20 Ecu no one can tune it ecu build date literally 20-07-02...... So given the stock ECU will the stock ecu compensate appropriately if I add a catted DP and intake or will I be leaning out the motor like the 90s? Yes I get it I won’t be maxing out my gains with out a tune. The question is simple how smart is the ecu?
