I have a pair of ECU's for my 575's that I ordered from them which they claim will make the engines rev to 5700-5800 and increase boost by 1lb. My engines have been running so good since I have had them that I was wondering if any one has had any experience with A Z on having their ECU's modified. I would like to see the extra speed that it gives but I don't want to ruin a good thing .
