Depending on the situation, I likely only use LC half the time.

You're not talking about the cap that comes wired into the speedo are you? If you are, absolutely no chance!! 
That cap wouldn't store enough power to flick the motor, let alone boost a 120amp start.
It's more likely that the speedo will eliminate the ramp up on the throttle. This is an old trick used on BR speedos for years - when in launch control, full power is applied in the first 5% of stick movement, and held for about one second.
There might be a variation on that theme that a BL can play with the phases and the timing, but in principle that's the best way to get a fast start. HTH

I haven't read the manual in a while but I think it does say that once the LC is activated the extra power is there until the throttle is released.

Has anyone tried the SPX with a modified motor. I believe it is rated to 5.0? I am interested trying it in 1/12 with single cell lipo but I don't want to blow it up.

If they haven't it's probably because it serves little purpose, the thing that makes the spx better than a tc is software super high timing advance ( great for stock class), something you don't need/want in mod touring, maybe 1/12 though
