need some insight, I am going to be installing my turbo before thanks giving, but I am doing it in small sections at a time since this is my daily driver. basically all I have left to bolt on is the turbo, mani, injectors, oil lines, dp, intercooler and pipes, wategate, bov. basically the heart of the entire turbo project. I have already done extras like, installing the bost controller, 255 walbro, all gauges, hondata, radiator swap to a 92 civic all aluminum.

what I need to know so that I can cut down on down time the day of the install is....
1. can I swap the injectors (450cc dsm) and sparkplugs (bkre7-11), then tune the hondata as naturally aspirated with the bigger injectors and get the idle smooth as well as partial and full throttle. I am thinking it'll work since at idle and really low throttle the car doesn't see boost even with the turbo.

and

2. if I can tune it this way does that mean when the turbo goes on I have to retune totally or will the extrapolate for boost work? this is all street tuning, with aem wideband uego gauge style.

thanks for the help
