My brother has an Sti he got it tuned at San Jose ,Cali. It's really fast now wow I guess he got a Reflash? Ecutek he says but what ever it is it made a really huge diffrents. He's just running almost stock TBE, intake, and a boost gauges though he's just running it on stock boost. He got it street tuned and others are telling him to get it dyno tuned. Why ? what's the diffrents i figure your on the road tunning is better than a Dyno right? or is he not gaining as much as he should on a Dyno? He ask me could he possible get more out of it?

 

We're supposed to vote on what your brother should do with his STi?

 

Street tuning is superior.

 

Yes, i ask to vote as an opinion and also as an experience tuner crowd

 

Street tuning is better if it's done right. Look at the big STI tuners like Rallyspec, they only street tune.
