Only done one day at the track since fitting. Running with bottle at half pressure it ran 14.4 rather than its usual 15.2. At full pressure it should be in the 13s
Everything is standard except a supra LSD diff. Activated by a button, I haven't even got a WOT switch as its for drag use and am only at WOT. 10lb bottle at 100hp lasts less than 10 minutes.
Lookee here

for info on compatible toyota diffs. I've got the non-turbo JZA80 Supra (SZ) diff (for auto or 5 speed manual). Bolts straight in but the final drive ratio is slightly different
The white one is in the UK, there's a yellow one somewhere.
There's some info here

Although it's not for sale anymore
I can't vouch for the accuracy of this info

There's a thread in the FI section "the Fish" where the guy has uprated his diff with bits from a supra diff

Look elsewhere on the same website at their big block crate engines 550hp for $6700. We only paid around $12000 for our n/a 730hp engine built to our spec.
