Excuse my newbie questions here. I have had hp tuners for about 6 months now and had a basic tune done, the basic tune removed torque management, removed speed limiter, increased idle by around 100rpm and slightly increased tranny fluid pressure. But I was curious as to the parameters that get changed to get a bit more horsepower? Is it a tune that must be done as a street/dyno tune?
Thanks and again sorry for my possably stupid questions
