I recently bought a 2000 ecsb Chevy with a bad motor. The previous owner removed and sold the turbo setup. I'm almost done swapping in a new 5.3. It has 60lb motron ls1 injectors an 02 ECM cobalt 2 bar map sensor iat sensor in egr opening and it's speed density tuned so no maf. My question is will I be able to drive the truck at all before I get it retuned. Also it was previously tuned with hptuners and licensed for the 2bar I was thinking of going with autocal from bb just looking for some input see what I'm up against.
