Yes i bled the system. I dont know why or how but, Yes i did install a 180 degree T-Stat from auto zone including a gasket the o-ring is worthless.. Not needed.. The car before ran in town or at highway speed'* at 200 degree'*. Now with the new 180 T-Stat it run'* between 180- 195 i would say, Cant really tell with stock bogus guages. I checked fuel milage and yes i lost 2 mpg (((( Big Deal )))) There isnt really a major loss of power but, it just feel'* slightly sluggish. The car run'* great otherwise.

But a 15 degree drop should not effect it.. If you feel that your car is loosin effiency and you want it back then reinstall the 195...

Did you change the t-stat around the same time you put the SSEi badge on?? Because it could subconsciously make you think it should run like an SSEi but only getting SE performance...
I'm sorry, had to do it....
If I were you, since all the info at performance shops and threads and other automotive forums completely support the idea of running a cooler t-stat, I'd concentrate your efforts into finding what else came unplugged, or anything else you may have done to effect performance, i.e. partial intake blockage due to a bumped tube, etc.
Good luck.

Dood, the extra weight of the three SSEi badges is causing the loss in MPG. Seriously, the O2 is only good for 50-60k miles. And there'* so many other contributors. I haven't seen ANYONE lose efficiency from this.
