Why don't you start out with an 02 Express van tune in 02 the Express vans came with the LT1 engine and a 411 PCM

Didn't the Vans have the vortec 350 in them and not the lt1? Would still have to be a much closer match for a tune then a ls car tune tho

Yeah I think you're right it was a Vortec but it's definitely a Little Closer then an LS car
