My current tune on my 02 is for 44# truck injectors if I swap to the car style 42# injectors will in need to retune?

 

What are the specs of both sets of injectors? are they both rated at 3 bar or 4?

 

not sure I have not ordered the other injectors, Im am tring to sell the 8.1 marine injectors first. The ones I was looking at were the racetronix 42# and it does not say what bar on thunders website

 

which 42? most racetronix are rated at 3 bar...

sense you guys are talking about injectors. through a tune can you apply more fuel? "stock"
my truck already has a tune in it and im thinking i could have my tuner apply more fuel,through out the whole rpm range.
thanks
