Engine won't rev?
Ok, so it'* not really a problem ( I don't think ). It'* just more of me wondering: Why won't my engine rev past 2000 rpms while holding down the break. It'* like this wether I'm in drive or if I'm in first gear. The engine acts like it is about to shut off once it hits 2000 rpms but then once it gets back down to about 1000 it revs a tiny bit back up to 2000. So does anyone know why it is like this?
and a random question.. Can you buy a digital gauge cluster for bonnevilles?

I dont think theres any limiters for when the brake is engaged, but I might have missed it when I was going through PCMs, I'll try it on mine next time I'm out

I know on alot of newer Chevys the Electronic-Throttle-Bodys have a traction control/power management protocol that will not allow them to go above 2000 rpms in drive with the brake heald in order to save the tires, brakes, and car as a whole should you loose control while power braking.
this could be a possibility, no?

not sure about the TCC/ Power Mangement thing, its not on the TB beacause it is not a drive-by-wire system, if it is in the PCM it would cost you a lot to have it custom programmed, is there a reason you want to get rid of this?

You are running up against the stall speed limit of your torque converter.
A few seconds of that is OK, but if you do that for any continuous length of time, you are going to seriously overheat the TC and eventually balloon it.
Are you doing this for staging at a drag race? If so, the only way to "remove the limiter" / increase the stall rpm is to get a higher stall TC.

I don't really care that it'* limited. I was just curious as to why my car was doing this. I also don't really like when things are limited. But I'm not gonna go too far out of my way in order to remove it.

Haha I'll admit that I do! I do my own tuning so I can make the little changes that I like, for example zeroing out the torque reduction on my performance shift tables 
I have to swithc back to normal shifts in the rain because I start to spin the tires if I don't
