i swapped injectors and chip over the winter. i turned the boost down to 16 and fp to 44. my first run i take it out, i gave it about 3/4 throttle and it gave me 12.9 kn on my scanmaster. i got out of the throttle real fast. my o2s were around 825. i tried adjusting it a little and same results. i had a thrasher in it before and it gave me a little knock but not bad. i think something else is wrong with it. so i plan on spending this weekend spring cleaning and tuning.
