This is a question for you guys that have run the gamut of swaping injectors from big to bigger to biggest....I'm planning a fuel system upgrade for a forced induction setup and I was wondering what the upper size limit was for a good idle and low speed/load driveability? Emissions isn't really a concern, but a stock-like idle quality is. I would like to go 60lb but I realise you can only shorten the pulse width of an injector so much before its just closed, how fine a measure of control does the stock ecm have?

Thanks.

Really good question...I would not worry too much about 60#ers. You might be able to call your local gm tech geek to find out exactly where the ECM parameters are maxxed.
