Do you have paperwork on the injectors that were just installed in the truck?
i did i called the shops where he lived till i found records. and turns out the previous owner bought his own and had them installed. So no warranty on the work or injectors. turns out cyl 1s injector balance rate is at +15 so i gotta replace them figured id do them all get plus 50hp ones so flow rates will be even. I appreciate you trying to help though
