Some engine management setups have programmable boost control, i.e. DTA and MOTEC and such. What's really nice is when you can do it by throttle position; you can make good strides in drivability (not like you care in a 1/4 car though). Either of those routes is pretty hard-core, but the option does exist with the proper engine management setup.
APEXi's boost controller allows you to tune boost via RPM, which is nice because you can roll it back at the car's VE peak to keep detonation down, and roll it up as the heads start to fall off and choke at the higher rpm's; adds to the power under the curve. That controller is stand-alone and like $550-600.
