i ve got a 92 rs with the lq5 swaped in the guy that had it last put the 350 chip in and and didnt put in the 55lb injectors
it wouldnt idle nicely so i changed the o2 sensor and i can still tell it is runnign lean. how much of a difference do you think i will see when i put the bigger injectors in latter this week and and set of headers?

 

350 injectors are 61 lbs/hr. 305 injectors are 55 lbs/hr. Alot of places have this in error and have the 305 injectors listed as 40 lb/hr. Those are 4.3 injectors. For comparison my 2.8 uses in the neighborhood of 37 lb/hr injectors.
