I... In your setup, your computer isn't seeing the added airflow that the porting has done for ya, therefore not adjusting accordingly. you have basically made the stock readings more efficient hense a few more HP. If you can monitor that airflow you'll be making even more HP by matching the fuel to it.

40 untuned HP is a "few"? What about the EEC's "adaptive control" feature? Know what that does? The only air/fuel tuning I need to do is at WOT due to adpative control. My A/F ratio was about 13.5 average - look at my dyno sheet attached. MAF is not going to make MAJOR improvements. But base timing and some fuel may - we will see next dyno.
