Im almost ready ( I think ) to go with the alcohol injection setup. I still may need to rebuild the turbo due to some oil in the intake pipe, and fix a small exhaust leak on the drivers side. I did a test run with some 110 octane fuel, and all audible knock dissapeared under wot. I think Im getting false knock due to the exhaust leak. As far as upgrading from the extender to a TT chip and larger injectors, please chime in and let me know if the chip-injector combo I purchased will help me prepare for the upgrade. Thanks for your advice.
