Yes, if you opt for power programming, Bryan at PCMForLess will adjust not only your timing curve, but he can also adjust your fuel tables, etc. He also does all the limiter crap, emissions deletes, shift points, electonic shift kit, etc, etc, etc...

Then you can get the next best thing to a dyno tune by recording some datamaster runs using a laptop and sending them to him via email. He will analyze your datamaster sheets and custom tune your fuel/spark/etc for you car. I know more than 1 person who has gone for a dyno tune and had the tuner say that they could not do more than about 3-5hp better than what Bryan had done by mail using datamaster logs.
