Green Top injectors still eating fuel (updated title)
Hey guys I recently switched over from my stock injectors to ford green tops and am getting bad fuel economy. (only thing I swapped was the actual injectors) 2004 M6 GTO (mods in sig)
I was getting about 25/26 highway avg on old stock injectors now im down to 20 with these! :shrug:
My tuner loaded the data he found on the injectors (bosch 42's) and stuff we might just need to look over short fuel trims?
I duno what to do bc gaining maybe a few hp isnt worth getting 20% less mpg any ideas of what could be to blame?
Car pulls great and accelerates great 02's are working and have a nice 12.5-12.8 air fuel. Its just like idle and low cruise rpms eating more gas than ever before.
Thanks in advance -Pete
