3406e 40 pin ecm

Mr haney would you please contact me about a 601hp file for 3406e thanks in advance

 

Hello I am new to the site. I am having trouble with power and fuel economy. Is Mr Haney still around? Could really use some help. Thanks in advance. My babe is Trevor

 

No, Mr. Haney has been gone for quite some time.

 

Thank you for the response. Can you point me in the right direction, or possibly help me out. The injector codes have been changed on my even. But the FTA/FT… values haven’t. Do to not having the passwords. I put a stage 2 big boss turbo on the motor. The boost gauge will roll back and it almost like I’m sitting still. New clutch. I just put 3.25 rears in the truck. Had 3.70. It’s got a 10B transmission in it right now. I have an 18 speed to put in truck in the next few days. My fuel mileage is roughly 3.8-4.5. 98 w900 6ts cat
