I'm looking for some suggestions as to what starting tune I could use in my 86 camaro TPI. I built a 355 small block with a semi aggressive camshaft, some alluminum heads, headers and a 3000 stall converter. I'm currantly using a $6E tune but having some difficulty. When I connect my autoprom up, its not linking up to the vehicle. Its not pulling any data so i'm unable to make changes. Any advice would be welcome.
