what is the best performance module for horsepower gain

 

I use the Superchips FlashPaq.It allows you to adjust for premium fuel or regular 87 octane,allows you to adjust the shift points,rev limiter,tire size and MPH limiter.ITS a great product.Superchips also has their web site set up so you can download updates to the tuner through the supplied USB cable.The horsepower gains are substantial,even in the 87 octane mode,its easy to use and allows you to return to stock in just a couple of minutes,which you need to do before taking your truck to the dealer for any maintenance as they often have updates to the ecm and will reflash the comp after maintenance.

 

Hey there Horseapples,

Did you set your Hemi to run on 87 octane? How's it run?

 

with gas prices the way they are mine is on 87 octane right now,it is still much quicker than the stock program,no pings or clatters from low octane gas,couldnt ask for more!!
