Nnbs injectors causing truck to run bad???
I put some Injectors in my truck from a 09 silverado and went ahead and switched the pigtails from the older injectors to ev6 style just getting ready for my new injectors to come in.well now the truck runs real slow it dosent have the power it used to and dropped. 5 in the quarter mile!Is there something different from the old injectors to the new ones?I looked up the part numbers and there both 24 lb injectors?I used a test light and I'm getting a pulse from all my pig tails so I know there good.Any idea why that would happen?

What injectors are they?
GEN 4 stock injectors are going to be larger than 24lb/hr at 58psi.
Of the couple of 09 tunes I looked through they are 29lb/hr at 58psi and the GEN 3 P01 and P59 use a base of 58psi for the IFR table. GEN 4 IFR tables will show 25lb/hr at 3 bar and 29lb/hr at 4 bar.
Talking non flex fuel vehicles here too, flex fuel truck injectors are around 38lb/hr.
