Hypertech Power Programmer 111 & 160 stat
So using it to then run a 160 stat, while it will adjust fan on temps lower....the "tune" part will do nothing. Way back when the local LT1 club had a dyno day. One car was done with a Hypertech/160 stat...lost 1 HP on the dyno
IMHO if you want performance you need a 160 stat, fan temp on lower...BUT a real "performance" tune (more timing & fueling) which a mail order tune from a qualified source can do. The Hypertech does not add any "performance" to the motor so just having a 160 stat and lower fan temps on is no benefit for performance using it. Yes in cold weather a 160 stat can leave you with little "heat" out of heater
Just lowering the fan temp on would make the car motor run a little cooler if that is what you want...but not necessary from the function standpoint of a stock motor.
