What are you measuring the temperature with? Driving around and/or sitting in traffic?
If you have a 180°F t'stat and you're only getting to 170°F in this weather, you must have a miracle setup....or too much coolant bypassing the t'stat.
well dave has tuned my chip for my setup so when i send hime the chip foir some more fine tuning I'll mention it and see what he thinks...I would have to guess that out of the 2 problems it would be the tstat, but I wont know until I diagnose...
I mainly wanted to know if ~170* was normal or not
