Skunk2 obd0 ECU's???

I was looking on Ebay and I came across these, http://cgi.ebay.com/ebaymotors/SKUNK2-1990-Acura-Integra-OBD0-PR4-ECU-B18-LS-GS-ECU_W0QQcmdZViewItemQQcategoryZ33598QQitemZ8049186595QQrdZ1.

I was wondering if anyone has used one of these before?? I have a 90’ GS with a B18B swap with some bolt ons and was wondering if this would help at all or atleast be better than the stock ECU? I’m not expecting anything near the claims on the auction but if you think it would help at all I would like to get one since there pretty cheap.

I also plan on going turbo in the future with around 12-14lbs of boost, would this work for boost also??
