I have an older AEM gear and I suspect that it is a y8 gear though, i have had nagging CYP code 9 problems (several new distributors, brand new wiring, new ecu etc) and the only thing that could be a problem left is mechanical issues. I guess that when I change the t-belt I will double check the gear and see if i didnt fuck it up when i put it in a while back...if you are making that kind of power i guess i have almost what i need.
