This is a good example of what happens when you do several mods at once.
We all have been there...
You are diong the right thing by upgrading the fuel side, but without the a scantool, there is no really good way to tune. A scan tool is a mod, after all, you want to get the most out of your combination-Right?
If you had a knock guage, we could see if you were getting timing retard, due to knock (most likely scenario) The extra air provided by the K&N needs to be dealt with, so why not consider a thrasher chip?
The screen removal might have messed you up, especially if the MAF went in backwards. (Don't laugh,-it's happened) The arrow should point to the TB.
One suggestion, Postons has a fuel guage that can be masking taped to the windshield for checking the WOT pressure. Under $50 last I checked, and something everybody should have..
