I swapped out the LS1 with this GM crate motor. Per the breakin procedures that came with the motor I need to put 500 miles on it before going above 4k RPMs. Once the 500 miles is up I plan on getting it properly dyno tuned but need a good tune for now. I have HP Tuners already. Below are my specs.

98 C5 (Whatever series PCM that came from factory in 1998)
A4 Automatic with 2.73 rear gear
LS3 376/480 from GMPP Hot cam crate
Lingenfelter 58 to 24 conv box
LS1 MAF
LS1 MAP
Longtube headers

Everything not called out specifically is whatever came on the new crate motor. I'm using the LS3 throttle body. Thanks in advance!

I am seeing that you really didn't get an answer here. I don't have the answer either, but am considering this upgrade myself if I can locate the long block. Supply chain issues are getting to be ridiculous. I have some questions for you if you are still around the forum or will take a PM?

I didn't see a question in his orig post which was 4 months ago.
Common swap, what are your questions?
