When I get a boost upgrade, will I need the boost timing control that comes with it if I have the AEM EMS? If not, can I buy just the pulley and belts.

Thanks

 

you will not need the BTC if you have a standalone like the AEM. if you want just the pulley, i think you can buy it alone. otherwise, get the pulley from someone other than JR, like from jim who makes the MVM pulley, or john from LHT makes a 5-rib pulley.

 

Thanks,

Will
