What kind of clamps are you using on your boots? One of my clamps blew half way off the boot over the weekend so i'm thinking if i'm gonna hit some higher boost I better upgrade the clamps!

i use peak diesel boot kit with there clamp also have a bd diesel kit the both rated for 100psi i have blown a few of the cheeper boots and have delt with clamps sliding off yea with your big injectors i would say 60-75psi could be seen as i hit 65psi on a hard throttel all the time all ao check your hose from the head to the afc as if the leak it wont full fuel. looks great
