Re: 5.3 SWAP Wiring Problem

you can send your PCM and VIN to a good tuner...and they will put the factory loads for your VIN into the PCM...once thats done, they tune it for your individual needs (fuel octane, elevation, reduction of torque management, etc.) before returning it to you. With this done a crank relearn shouldn't be necessary.

ALL of this is one of the reasons I am putting a carb on my LSx.
