Blowing bcm fuse after diff ratio change

[jpawgy]

VX super 6 auto
mods: 69mmTB with chip, CAI, 3inch exhaust and pacemaker and high ratio rockers
lowered 3.9ratio diff gears

After install of diff gears the bcm fuse in engine bay blows upon heavy foot in lower gears seemingly when it might lose traction. TC on or off, fuses out, cut 27 wire no difference.

No fault codes in Envious engine
Fault codes using Envious body : instrument cluster 0 unknown code
16 ABS/ECT fault logged in ABS/ECT ECU. clear dtc. (I think this is cut 27 wire)
body control module 17 Serial data bus fault (clears)

And it only started doing this after the diff gear change? Was anything else changed at the same time as the diff gears?

Have a good look around the diff and see if any cables for the ABS sensors are damaged.

yea diff rotation or data from it will have nothing to do with a fuse, must have been something in the install pinched or damaged
