I've got a 2005 4.8 swap into a truck, it has a cone intake and headers, other than that its pretty much stock.
The vehicle is very hard to start hot or cold, have to give it a bit of throttle before it actually even tries to idle. It will take about a good minute before the idle evens out and that's only when the PCM is adding 50+ of fuel on the trims.
I have not messed with anything on it and want to see what you guys think.
Injectors were ordered from ebay part number 25317628 . I'm thinking they may be questionable as far as the flow rate and stock data not matching to them, the truck seems to want more fuel at idle. alot more fuel!
The tune and scan are attached.
Thanks in advanced for all the help.
