At WOT, it feels a little sluggish like its running lean. On WOT I get lean codes bank 1 and bank 2. Anyone care to look what I could change? I attached my stock tune and the tune im running. Would it help if I had my actual values of the 02 sensors and MAP data? Im just trying to get the most power with a stock setup besides K&N cold air intake. Any help would be greatly appreciated.
