You speedometer wil be correct, you can lift your rev limiter, and disengage your speed limiter ( 112mph) but really without goign to indepth wiht the company, don't expect much, I didnt. I asked for firmer shifts, it felt just like when I sent it out. I want it tuned at a shop so they can physically dial it in. You won't get any better gas mileage without first doing some head/intake work on our motors, the intake ports are god awful from the factory. when I was goign to buy Tim's heads off his drag car, he had astock cam in the car, and with an intake/heads ported and what not, got about 30mpg!! so for our cars it's not so much how you changethe computer, you got to change some parts as well.
