I have a hypertech... Is is poss to buy the smarty/superchips programmer and stack these? I heard some guy talking about doing that thinking it was impossible and then saw it in Diesel World (i think) on that blue sleeper truck and it says something about piggybacking 2 programmers..... and then still having the box (chip) in the engine..... shine some light for me!

 

no you cant if by programmers meaning the ones you plug into the OBDII port, it would just erase the first one you put in there...now if you have a chip like an edge juice you can

 

That would be some mighty high timing!

 

thats what i was thinking.... maybe is just read that wrong. anyways. the guy who wanted to buy my hypertech was saying he was gonna stack em and that didnt make sense to me but. what does ya know... anyways. thanks guys
