Fuel Tuning

Has anybody on here done some of their own fuel tuning? With the magna flow exhaust and high flow air filter, I have noticed that the fuel trim does run a bit lean and the acceleration could be better through out the whole power band. I was looking at magnumtuning.com products which seem a bit gimmicky. I was also trying to find out if dynojet has a power commander as well. So far I have not successfully contacted a shop here in Denver to discuss fuel tuning professionally but that is to remain an option as well and am open to suggestions.

Thank you in advance for your input!
