acceleration issue??

[1G90AWDTsi]

My car had 750cc injectors installed in May along with DSMLink and a re-chipped ECU. When the car went into the shop it was running at 14psi with a manual booster and during the setup the mechanic lost part of the booster, i didn't care about it so i told him not to worry about it and it was taken off so now I'm back to factory psi (i don't care about that). anyway before the car went into the shop, it never had a problem accelerating even under WOT.

Now though, it accelerates with a sputter. Is that solely a tuning issue that can be worked out at the dyno?

It sounds like your fuel settings on dsmlink are not set or are set wrong. Make sure that your dead time and global settings are set correctly to compensate for the larger injectors.

Manual booster? do you mean manual boost controller?
boost leak? fuel settings?
too many variables there for me to suggest something more specific.
