Ok guys been having an issue. I'm down to a few issues left. My car is breaking up badly at 5 k. What I've done so far was replaced the plugs. Did a boost leak test and also readjusted my bov. Its an hks ssqv recirculated into the intake. I'm thinking I'm losing spark and don't know if this has been heard of. My battery is in the trunk so idk if a bad ground could cause this or if my coil is worn out. Any help is greatly appreciated. Thanks
