Hello,
I had recently replace the seal on my injection pump.
Have my intake manifold cleaned out and I also did the diesel purge.
I have seen my mpg going from 47mpg to about 38mpg.
I wanted to know if I should do the injection quantity IQ adjustment via VCDS (I have the VCDS Lite and an ebay blue plug).
My IQ is at 4.6 mg/str. I understand that the IQ should be between 3-5mg/str.
What is the limit that I can do as far as adjusting the IQ with VCDS?
Should I also do the hammer mod?
Would doing these help with my mpg?
Thanks to ALL for the help.
