Need help! I have a 18 SG. After market high air cleaner, rinehart slip ons ( i removed the cat and the baffles) and bought the dynojet powervision 4 tuner. I was told my dynojet to select the tune with full exhaust, 2 into 2, high flow air cleaner and rinehart slip ons. I've even ran the auto tune twice. It's still consistently running average 370 f . The temp outside is in the 90's but is this ok or even normal for this engine? I did put the baffles back in just to see bc i kept hearing about backlog but didn't change anything except make it quieter which I hate. When running autotune I do keep seeing it say engine running at high temp and i did have a dtc that said engine oil pressure sensor shorted low so I've ordered a new sensor but will that make it run hot?
