| Duel fuelers on a stock bottom end is a bad idea and a waste of money. Your stock cp3 has more than enough potential alone to ruin a stock motor. You could run the 71mm turbo with some 40% injectors and stock cp3 and have a pretty reliable setup. Im assuming its an aurora 5000 turbo?? If so, you may want to look into a different turbo, those can be pretty laggy unless you throw tons of fuel at them. I bet you would have better luck with an s472.

| I figured out a 71 mm won't work for my lb7 because its Vgt so I'm getting a s366 for my lb7 I already bought the combo but if I don't need it I don't so keep posts coming I love learning

| Yeah I'd get some 40% nozzles and ditch the dual fuelers. There's really no need for them.

| What if I didn't get injectors ? I feel like right now I have more then enough fuel I wanna burn it up would a 66 limited to let's say 45 boost obviously with head studs be a good way to go about it ?
