Dewolf Software for m4.4 tuning is TunerPro, it's a free download, full version. All the info and tuning files you need to get started are available online.
You can remove 1st gear torque limiter with a single click, calibrate for bigger injectors and maf. With extra files and a wideband you can have full closed loop fuel control. It's not the easiest to use, but if you have some mild experience with it you should work it out. I fully road tuned my car by datalogging, making changes, more datalogging, etc etc.
