so i swapped a l67 into a regal ls and it seems that it is running super lean according to what chuck said. I need some additional eyes on the tune to see if we can get his car going in the right direction. I have alot on my plate right now so any additional help is greatly appreciated.

There is only 2 things that I can think of that might be causing the issue
1 we put a ported 99+ tb in the car but used the stock 97 MAF. but based the maf values off a stock 98 tune which I assume is the same as the 97 map. If its not that could be alot of the issue.
2 I think he has a couple header leaks he is addressing.
