Injector swap questions
I am swapping the injectors in my 2000 C/K truck with a 7.4L engine. What do i need to change in my tune besides the injector flow rate the stock injectors are 19.4lbs/ H and the new ones are 23.3lbs/H
Here is my stock tune and my current tune. the injectors I put in are GM part number 25313185 and the specs i could find on there are lbs/H 23.3 cc/min 244.9 grams 176.1 43.5 psi
