We have a data print out of our car with CAI, base tune, and larger injectors. The car was tuned for the larger injectors at the time, the run was basically to see if we overcame the lean issue.

It's an excel file with HP and TQ if interested. The graph we had that day was over time and not RPM, but the data is.

Basically when we had the CAI and ECU tune you would still be able to drive it and it would rev out, but when checking the actual AFR we found them peaking into the 15 and up range.

When we added the larger injectors our AFR went down to about 11.5-12.5 which is way too rich. We put down about 235HP with that AFR. With a tune for teh larger injectors we are in the 13-14 range, which is more where we would like to be on these cars.
