I have a 2017 SHO that’s been flashed by hydrotech but kept the stock rev limiter. The engine is connected to my Lowrance and most of the time, I see 145 degrees which is similar to what most people seem to run. However on long WOT runs (>5 mins at WOT) Temps start creeping up to 160-170 and sometimes close to 180. Typically I run 15 psi at WOT. Water pump is brand new (was doing the same with old water pump). I cleaned the thermostats and flushed water through all the lines, but am still having the same temps. Curious if anyone has seen similar or has ideas on what else to check. Also for those with flashed ECUs, what temps do you see at WOT?
