how much differece is there between the to will it make much more power with the 180cc?

good question. i think the larger injectors will make more power but you need the supporting parts to do it(bigger turbo,larger fuel system,ect...)

How heavy do you tow?

ive heard that you can run 180's and just tune out the extra fuel.

True to an extent yes

I have 185's, and even with fuel pulled(as much as possible or it runs like chit), towing sucks. Lots of hills where I roam though.

155's can be tuned to make quite a bit of power from what I have gathered. I have a buddy with 180's in his truck and a II stage 1 turbo ( he needs a larger turbo ) and the 180's have a ton of fuel even pulled way back. What you really have to look at is what you want to do with the truck. If you still tow with the truck, I would just stick with the 155's and add more fuel to them if possible. If you are looking for a little more performance out of the 155's, try getting your FICM tuned. Eric can make the injectors stay "ON" longer (Pulse width) and get that last little bit of fuel out of your injectors. Hope this helps some.
