Converting to LS7
Going to replace a stock LS1 and with an LS7 (24 tooth reluctor) with all of the goodies, cam, ported heads, PTB, ported intake, Kooks, 100 mm mass air sensor, etc. What do I need to do for a starting spot for tuning. I know that the Halltech mass air sensor requires a change in programming when added to a stock LS7 but this ecm will have a stock LS1 tune to start.
Please educate me!!!

This will obviously not be a stock LS7. With a cam, head, maf ect. change you will need , from scratch, a custom tune. You could try a mail order tune to start with from an experienced tuner like Charlie Williams then tweek the tune from there. Or just trailer it to a tuner when you get everything installed.
That 427 should be a world of difference from your old LS1!
Hope all goes well for you!

They just tuned my 2000 FRC after cam/header install and did a good job.
