Warmer Temps

[Ponderosa JT]

Installed my performance upgrades last Oct when colder temps were coming into the Chicago area. Now that it is starting to warm up, I've noticed the temp gauge is running about 10 degrees warmer than it it did last year. Will a tuner on a 40-65hp setting cause the water temp to run a little warmer, lets say 195-200 vs 185-190? This is unloaded with temps in the mid 80's. I'm planning to put the Predator back to stock and see if I see the temps go back to where they were last year, before the improvements.
