Hello,
I just bought efi live and I have no clue on how to do any tuning. I live in el paso tx and the elevation is about 4000ft which is crazy. Now I have a 1998 pontiac Transam WS6 A4. I basically have a ls6 engine out of a 2003 z06. I have 3.42 gears, lid, and pacesetter longtube headers. Now I wanted to know how hard it would be for me to tune the car? As it is right now it runs good But I think a tune will make it run even better. I don't have any rear O2's.
Thanks!
