I have a 03 lb7 with 4 inch straight pipe,cold air, and banks 6 gun with pda.
I had made a boost fooler valve to increase boost and it worked an extra 2-3 psi wich put it at 25 psi max. but it should have been 7-10 psi about 30-31 psi. i wanted to see if i had another problem and unhooked waist gate compleatly, pluged boost hose and test it and still it wont go over 25 psi on speed loader tune,there should be plenty of fuel.The guy i got the banks from was very very noligable. He showed me how to make my own boost fooler valve to achieve his max of 31 psi.
Does any one have any idea? wtf:
