I put a 195 in the 02 Ram 5.9 I had.. Napa Perscribed. Went back to a 180. Just to hot for mid south Fla. Didn't notice any adverse affects, just the temp a Lil lower!
OP stated OBD I. I’m sure these behave differently.
But - to figure this out , You would have to monitor real time w a scan tool. - Something will be out of whack. If not, something the old OBD I doesn’t monitor.
