who does speed density chips?

[ct67_72]

and how do they work on the street? I would like to simplify the system a little and have ease of tuning but still maintain fuel mileage and driveability.
also if there is something available how is the tuning with it?
Ive used an AEM EMS on all my other cars so far but I dont want to go that far on this one, oh and my combo right now is stock turbo and intercooler, 50lb injectors, downpipe, intake, exhaust and 2400 converter

Eric has one for sale. turbotweak.com

Not sure how it is for a daily driver, unless you like to retune when the weather changes.
