'03 chevy express van stock tune

does anyone have a stock tune for a 6.0 chevy express van? seams like i have a few dtc's shut off i don:t know if they are supposed to be or not

I have an 04 if that will help

i think it should be the same '03, is the first year with the ls motors in the vans. can you send it to my email? [email protected]

sent

thank you

I have a 2007 6.0 .hpt file from an Express van that I would be happy to send.

I'd also be interested in seeing a later version if anyone has one.

There may be improvements in the stock tune that we could learn from ???
