MY 2003 HAS COMMON RAIL FUEL INJECTION.ONE CONNECTION OF THE BULLYDOG BOX CONNECTS TO THE FUEL PRESSURE SENSOR ON THE FUEL RAIL, BUT THERE'S ALSO A FUEL PRESSURE VALVE THAT RELEASES EXCESSIVE FUEL PRESSURE AND LOOKS LIKE IT'S MECHANICAL. I WAS CURIOUS IF ANYONE HAS TAKEN IT APART TO SEE IF IT CAN BE MODIFIED. I BELIEVE PIERS DIESEL HAS A HIGH FLOW VALVE FOR THE OLDER TRUCKS. I MIGHT BE LOOKIN INTO THIS IN A FEW WEEKS

 

BRAND NEW MEMBER AS OF TODAY. I'LL BE RIGHT BACK,BUT I HAVE A BULLYDOG BOX, 100 HP INJECTORS,NO MUFFLER, K&N, AND DTT STUFF IN TH TRANNY.

 

THANKS FOR THE WELCOME. I HAVE THE 48RE, UNDER FULL THROTTLE 2ND IS A LITTLE HIT 3RD SEEMS LIKE IT PULLS BACK A LITTLE BEFORE IT SHIFTS AND 4TH HITS THE HARDEST. ACCUMALATOR PISTON AND BILLET SERVO. THERE ARE TOO MANY THINGS THAT "SAVE" THE DRIVETRAIN, I THINK IT'S DIFFICULT TO FINE TUNE. MY POWERSTROKE WAS EASIER. I THINK THE INJECTORS ARE DIESEL DYNAMICS, A SHOP HERE IN MIAMI WORKS ON MY TRUCK,
