New to this group and a novice tuner.
Working on a 1999 Dodge Durango SP360.
Running very lean, ie) 17-18 at idle and around mid 20's above 1000rpm.
Has a larger throttle body (plug & play), and 40lb injectors.
Any help in where to start looking would be greatly appreciated.
Thanks
John
Is it fly by wire throttle body?
No, its direct cable.
What ecu are you using. What's the difference in size with the new throttle body in comparison to the original one.
It has a Kenne Bell supercharger. Found out that the piggyback ecu was bad and someone removed it. The conjecture in the shop is that the new injectors were to make up for the loss of the two 100lb injectors when the piggyback ecu was removed.
The new injectors are: Holley 250R150A 42lb/hr
The larger throttle body is a HUG 5504 - 1007 cmf. The O.E.M. 740 cmf.
The ecu is factory.
I've attached the ecu read and a short scan file.
Thanks for any and all help.
John
