I am still-using the VBoost, also. Sorry w/o removing the carbs I dunno what the jetting is, but I have the DynoJet Stage 7 inc. K&N individual pods. It seems to pull harder than stock, but I haven't dynoed it since this:

Since that fateful, expen$ive run, I have
- torn-down the engine (helped-to do it, my mechanic Steve at Under Pressure in Dania Beach FL did the assembly)
- undercut tranny installed
- new clutch-PCW extra-plate & HD spring, stock OEM friction discs
- COP's from Gannon, new plugs come w/them, thanks, Gannon
- head-job w/0.005" taken-off the heads
- replaced the rear intake cam (obvious why)
- UFO 4/1 Dragstar head & mid-pipe w/a Franken-can(ister) exhaust
- the Stage 7 kit
- radials
- Superbrace
- I had already upgraded my '92 front end to a '93+ including FZR1000 brakes & 298 mm rotors, & new master cyl
- replaced the stator & pick-up coil (already had-done the R/R)
And I had already done other things prior to that like rear Progressive Suspension shocks & a 7" round halogen headlamp.
So, w/a freshened top-end and the UFO 4/1, I am gonna go out on a limb and say I expect I probably am getting about 10% over what I had, say, 10-11 RWHP in-addition, to make it ~120+-.
The first jets we tried didn't work as-well so it was leaned-down a bit, I
think the mains are now 152.5's (Mikuni). If I have to remove the carbs, I'll take a look.
Something I did notice, it didn't seem as-if there is as-big a kick in the pants from the VBoost w/the Stage 7 in-place. It does make synching the carbs easier. It will pull easily and hard past redline, except I have a DYNA 3000 ignition box/rev-limiter on it now.
