there are a lot of different options for tuning these things but most of the people who have a stock sr with bolt ons dont bother tuning them or they get a generic reflash.
Some of the better options which can be tuned on the dyno are.
Apexi Power FC
HKS Fcon Pro
AEM EMS
Greddy Emanage
Nistune
those are all fully programmable options though some replace the factory ecu and some are just add ons. Of course what system you run also depends on what motor you have and what your goals/ plans for the car are.
I know allot of the people on here have enthapy tunes where they get a generic map based on what injectors maf and turbo they are running.
