if you are talking about the injector spreadsheet that RedHardSupra found and then spiffed up, its pretty basic. If you don't understand how it works, you probably should get some help tuning your boosted setup...bad tune and boost usually equals boom.
anyways just plug in the numbers for your injectors, which you might need to lookup from the manufacturer. those 60#'s are prolly mototrons which are common and have information readily available. in fact, the spreadsheet from Marcin comes with those #'s plugged in already.

try this one man, I tweaked it by adding the lb/hr which is what you will use in HPtuners if you aren't in metric mode, this saves you from having to switch to metric mode.

I believe the mototron 60's are rated at 3bar pressure, which is 43.5psi (our stock fuel pressure is 58) so you would put 43.5 in for rated, and then 58 in for actual unless you have made changes to your fuel system and you fuel pressure is no longer 58 and finally 60 for injector lb/hr flow rating. The spreadhseet will then generate a table, and just copy the lb/hr column or (g/sec if in metric) into HPtuners and you are good to go.
