5.3 with 4.8 PCM I have a 5.3 but a 4.8 computer. I still need to have the computer flashed for my LSX conversion.
Can I run this combo without adjusting the tune or do I need to have something done when it is flashed? Can a tech changing the setup of the computer load a stock 5.3 tune?
Any input would help.
Cheers
Bret

It is close enough it will probably run if they both have the same injectors. I highly recommend getting the pcm flashed with the correct tune though. If its an engine conversion the pcm will have to be flashed to delete vats and a few other things at as minimum in order for it to run. If you mailed the pcm to us it would be $200 + $15 shipping with a 1 day turnaround time. That would be a full mail order tune for an ls swap, not just deleting vats. If you want just vats deleted or have any specific questions feel free to call us or email us. Our information is below in our signature.
