I know this works on diesel trucks, and I have to wonder if if might work on a HEMI. A Jet chip for example is a piggy back style unit sitting between the ECM and the harness, while a Superchips unit is a programmer. Is it possible to use something like a Jet chip and a Superchips unit at the same time?

 

The Superchips expressly tells you not to mix it with other chips/programmers. Dunno if it would work though.

 

I would think it would lean out the air/fuel and then go KABOOM! That's what I think.

 

Well they both have timing adjustments built in to their programs, so that would probably be a problem, uless you could use the superchips just for adjusting shift points and what not, but I dunno how the superchip works exactly as I have never had one.
