I have a set of 6 MSD 50LB injectors for sale along with a Turbotweak chip that was cut for the injectors. Injectors have 2 trips to the track on them (about 2000 miles total) and the chip has less than 1000 miles on it. Never had any problems with this set up but I'm out of fuel so I must go bigger. Selling everything for $325. shipped. Thanks
