apparently ford made 2 versions of the ofac ecu and reversed some sensor input on it (cant remember ask Stu or Kenny) but when superchips did there 195 chip it was on the version 1 but as mine was version 2 the 195 chip doesnt work correctly and superchips never cracked it hence my boost used to cut violently at 15 psi when it shouldnt of done.
