About any shop will up a DDEC 11 even Williams in Phoenix DD released the strangle hold on the DDEC 11 in 2002, CARB in Ca is different story
If he lived close to me I would not have a problem turning him to 400 hp with a DDEC 11 but I will not touch a V or above, there's not much you can do with those anyway unless it is a offroad ECM
