I have the T28 but did not mod the fuel system (still on 330CC) at all as I know you would need advance dyno tuning. We did pull all of the plugs when we took the vavle cover off and bob reported I was running lean (which makes sense as I would like more bigger CC injectors.) In my mind though it still is off as it does not really build power right now… I have a apexi stand only and can check most every sensor in my car but still need to invest in the wide band to see where I am at. I thank you all for the suggestion and will keep those of you care updated on this painstaking as you will see it in action for the first time every this year.
