Will This Work????

Has anyone used this before and does it work as good as other EFIEs?? I have a 07 Chevy 4.8L and installing HHO on it: http://cgi.ebay.com/ebaymotors/1999-Chevy-Silverado-1500-OBD-Fuel-Saver-HHO-Kit-EFIE-_W0QQcmdZViewItemQQhashZitem4aa3181574QQitemZ32056 3844468QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccesso ries

I have a Ultra Gauge (http://www.ultra-gauge.com/ultragauge/index.htm) that displays the MPG and hooks into the OBD port. Will that EFIE give my Ultra Gauge false readings in any way??

I am installing the HHO and this on my 07 Chevy 4.8L Truck.
