Joe is correct, here is something he doesn't know though. Eileen is on vacation. We can answer most questions, Joe has done way more installs on Kappa's than I have, I have done more non Kappa cars. I know have 14 HP Tuners credits so I can tune all the cars in the family. I love HP Tuners, Lyndon about had to shove it down my throat way back when. I have the Pro version, not sure it has many advantages for a Kappa owner, it has quite a few if you have a GM big block, it will do live tuning while the car is running. I wish you could do this on the Kappa, Lyndon could make a new tune in about an hour. My car is at the dealer right now with a busted fuel pump, they told me it would have the stock tune in it when I get it back, I said I don't care. I will just reload it. It is going to run like crap as it has no cat, and they haven't noticed yet.
