Got myself in a bit of a predicament. Bought a 07 classic ext cab 4x4 lbz (my dream truck) last week. It came with a straight pipe and efi live with the dsp5 switch on it. Previous owner had it installed by a shop instead of buying the autocal device with the tube loaded on it which means I have no way to put it back to stock. I planned on having my “smog guy” take care of this issue but he can’t even get through the efi live in the ecu. I’ve got the stock exhaust with the cat but no way to get ecm back to stock. Any one have any ideas? Can I buy a autocal device with a stock tune loaded on it so I can smog this thing? Wish I had a house in az I could register it to. Any help would be much appreciated this is driving me insane.
