Sig is updated. Unfortunately I think you'll need to use TunerProRT because I'm not sure tunercat has the base pulsewidth multiplier defined. Also the readme is written specifically for TunerPro. If you have any feedback feel free to PM me or post here, I don't think anyone has used this other than myself.

I didn't catch the supercharger in your introduction post - so are you running pure MAF or do you have patches for >1bar MAP (if such a patch exists)? Intercooler?
