Can I run a superchip 1745 on level 3 with regular gas and not hurt anything?

 

if it is designed for premium, yes you will damge the internals of the engine,why would you want to do this?

 

becuase I can barely tell anything with level 3.

 

On the performance setting, I have heard, if you use 87 octane instead of 91 the valve may start claddering after a while. I started running 93 on one fill up and 89 on the next. My has not had any trouble and I've had mine on about 4 months.

 

you said you could not tell a difference???? I noticed the first day. I left it on stock and punched the gas to the floor from a dead stop and then put it on performance and do the same thing.
