what do u guys think about the 160 thermostat

 

It may cause operatonal problems with the engine sensors and systems, since they are calibrated to existing setup. May also reduce fuel mileage and cause accelerated internal engine wear and contribute to degradation of engine lubrication oil. Modern engines are designed to use temps of around 100c + with high pressure in the cooling system to raise boiling point of coolant. I would not do it.

 

The ECU wont go into cold mode and it'll cause some minor fueling issues; it may stay in open loop. Basically, the only thing you may encounter is poor fuel milage. There is no notable power gains with this on a stock motor with some bolt-ons.

 

i would use a 180 if adding more boost but the stock one you wont have any problems with

 

180 is stock on the Gen 2 Lightnings.

What Matt said.

Basically, most highly modified guys do it as a preventive measure to help, no matter how small a diff it may be, lower the chances of detonation.

You need to have it addressed in your custom tune so it won't cause problems on cold mornings.
