If my cruize BLMs are low (109) all around, and my o2s are high (high 800's) should I be adjusting my fuel pressure or adjusting the BLM correction in the extender chip? My fuel pressure is set at 45, and im running 55# injectors. Would they both have the same effect? Or is one better to do than the other? Also, a leaner MAF Base would only effect idle correct?
