If anybody had read my post you would have seen that I did not say the 5176 kit could not be adjusted I said it was not shipped as an adustable kit. We have modifed these dry kits to make over 300hp. Oneflyn95 what was the name of this rep that knows more then the techs and who what was the name of the only tech who you claim knew the magic behind the 5176? You're telling people they need to change injectors. Which they should do if they are going to try and go bigger then the 67 jet. But at this point the kit is not stock a guy can't just buy the kit and put it on and try to go to 175HP. When you have a dyno and a wide band you can do alot of things that normally wouldn't be recommended like I said earlier we have used this same basic set up to make over 300HP single nozzle dry kits. The whole point of this was not to say that the kit did not have the ability to be adjusted but that it did not come as an adjustable kit. You may have experince with this kit on a dyno but most do not. You can belive what I tell you are can't that is your choice but keep in mind I deal with nitrous every day everything from go-peds and chainsaws to pro-mods.
