Hey all. My issue is I just did a 2.4 upper, CAI, and flex kit and my fuel pumps are maxed on E60. I have read a couple different posts about the AEM drop in fuel pumps with success. Right now I am on the fence of buying a JMS voltage booster or buying the AEM fuel pumps. If I do a direct swap of OEM pumps with the AEM pumps will it set off the check engine light?? I don't really plan on doing more mods, at least not for a while. Thanks for the help.
