I have spent a bit of time on the dyno playing with mine and while I dont have a to4 to deal with I found that the motor ran extremely rich. The technican did not play with the 'flapper' spring but did try and correct some of the overly rich mixture through the adjustment that did exist. Remember the new injectors that you have in mind are about 50% larger than the original equipment. Maybe thing could be made to work at higher boost/revs but you run the risk of it running like a dog down low. If I was you I would be tempted to put it on a dyno with a good mixture meter attached and get an idea of how it is behaving! You may be surprise - there may be good hp to be found with the standard injectors. One thing that you may be interested in. When we were playing around we removed the hose that provides the 'raising rate' to the fuel regulator and carefully monitored mixture. At the point where we just commenced to get boost we got to just over 14.2 (from about 12.9). But the real surprise is once it got on boost it changed from low 11s to low 12s. I picked up 13 kw at the wheels and it really smoothed out the power delivery. On shootout mode the dyno gave 140kw at the wheels. Note that with the tiny turbos by the time it got to max power at approx 7000rpm, boost had dropped away from 14psi which the wastegate was set at, to around 9psi. A problem u will not have with your setup. Anyway just a thought if you do decide to try bigger injectors, although my gut feeling is that if you are happy to keep under 14psi with you new setup that things should cope.
