If the trans runs better at 190 then why does mine run at 140 from the factory with the factory trans cooler? The higher temps for the motor and trans are for lower emissions and fuel economy. Look at the mods that are done on here to increase air flow, timing and fuel. By your logic these motors are tuned perfect from the factory in every respect and aftermarket mods will only make them worse. Which is far from the case as a few simple bolt on mods easily gets 50 more HP out of these motors with better trans shifts and in some cases better fuel economy. Unless you think the thousands of people on here that mod their truck are part of a vast conspiracy. If Ripp superchargers was able to get a 40%+ increase in HP with a simple bolt on kit and thinks its prudent to put a 180 thermostat in there install kit than it must have merit. These engines are tuned to meet strict EPA standard for emissions and MPG (to achieve high CAFE standards) not for all out performance. Also there are many post with several runs on the dyno. The first dyno pull always has the highest power output when the motor is cold. The subsequent runs show lower and lower power outputs as the engine heats up. This can been seen on the Ripp website where they did 3 dyno pulls in a row on a stock motor and the first (cold) run had the highest power output. Im not making this stuff up, the results are there. See for your self:
