Yeah a manual boost controller would be your best option. It would require you to turn the knob under the hood to adjust boost if you had multiple maps. The AEM TRU-Boost isnt super cheap but its both a gauge and a boost controller. You can store two boost settings on the unit to allow for easy switching.
A manual boost controller is going to allow the boost to come on as hard and quickly as possible. Some of the electronic set-ups allow you to adjust how quickly boost hits which could be beneficial for higher boost/higher torque stock block set-ups to help keep from stressing the rods more than you have to.
