Need help with injector sizes!

[muddy650]

I am new to the injector market!

What is the difference in 175cc/stock and 155cc/30% ?

I am looking at some and their really isnt a whole lot of difference in price!

Which ones would be better for me to get? I have and 03 Turbo! But I plan on towing some and I dont want to have a problem with EGT's! I would like to do a Powermax, but the wife is about at the end of her rope with these mods since I just had studs and gaskets done!

The first number 155,175, or 190 is the size of the injector. Stock is 135. The second number is the percentage over stock that the holes in the injector nozzle are. Which one would be right for you depends on the weight you plan on towing and your fuel pressure.
