Log is a 5.3 tahoe stock everything only has a flow master. I have been researching and studying the forums and have re scaled the v.e table and maf recall. I have notice a little better throttle and slightly improved fuel mileage but i still have spikes of kr under light throttle and load. I cant hear any pinging and i dont know whats considered normal or how to eliminate it. i did notice while driving the kr will spike from 0 to 7.5 with a 100 rpm increase I have added timing to the whole table via scanner logs but pulling the timing from the cells with kr seams like it will make my timing choppy unless thats normal or ok. i still need to get around to adjusting the pe to a more savy 12.2 or so..jog around home after ve and maf recal.hpltq, manage adjust#1.hpl
