You may be familiar with the GMT800 trucks GM built for Mexico/South America with the 350. Looking for a stock GMT800 5.7 4L60E file for a 4.3 to 5.7 swap that is underway.

I have been looking for one of those for about 6 years. If you do find one, I would love to have a copy.

Maybe a VIN number is available for one of the export GMT800 trucks? I was thinking maybe Tuner Cats would then be able to sell a .cal file for the export GMT800 truck VIN?

I would be willing to split the cost if that is a possibility. What I have always wondered is---Do the exports use the 1mb PCM or the older 512kb PCM?????Originally Posted by dave w

I did some digging and I have been unable to find a GMT800 after 2002 with the L31 although I am fairly certain I have seen GM literature to their existance through 2004.
$7K would buy you a really nice looking 2002 GMT800 L31 to reverse engineer.

Since that is a 2002, it probably uses the 12200411 PCM and the same or very similar calibration to our Express Van. A 2004 Vortec 5.7 calibration is what I would like to have if it exists.
