Been searching and asking questions about the JRSC and aftermarket tune. Based on what I have read and been told, the only way to use an aftermarket tune and make the JRSC work is to have an aftermarket MAF and injectors. Is this a true statement? All I want to do is install the standard JRSC with no intentions of upgrading from that. If I have to go the MAF/Injector route what is a good source for these items?
