I want to start modding my evo, and have a question about the Dynoflash. My evo is currently stock, and Im in CA so Im running crap 91 octane. Will it be worth it to get the reflash for a stock evo on 91? Or is the dynoflash used mostly to tune the car once additional aftermarket items are installed.....Thanks for your help...

 

Even on a bone stock car it helps. The car runs extremely rich from the factory. Not to mention he raises the rev limiter and removes the speed governor. Definately worth it!
