You have alot of work to do. U increased the air to the engine, now the ECM is adding fuel. Now u have to learn how to tune it. Unplug the maf and change the ve table until the stft + ltft are negitive. THen plug in the Maf and tune that. U will have to read the stickies and make the changes. People will help u if u have trouble but they will not fix it for u.
