Yes do you have a Diablosport tuner? Its the best device to tune with on a SRT-4 at the moment. You simply get one, upload your stock tune file from the car put it on your pc and send it to them via email. They will also ask your mods and such to get a baseline tune written and send a tune back to you. You then flash to your car. Do some datalogging with the DSP and send it back to be "fine tuned" till you get it running how you like.

Its not that hard and yes its what I did lol.
