well as the subject says iam about to go auto to manual and I think its about time for a fuel injector upgrade seeing as now iam hitting high duty cycles around 90 running at only 12-13 psi. I have a extra set of 850's which I was planning to run in the primary and just run 850's all around but after searching alot more ive heard alot of bad things about doing this. Ive heard alot about bucking and just general crappy behaviour when running the quad 850's, so now iam wondering is this just a tunning issue or does everyone have to deal with this when they run large primaries. If there is anyone running large primaries please give me some imput here.

thanks

It's just tuning. There are many single turbo guys running 850/1600 setups.

Best to stick with 550's in the primary for idle/low end performance and 1300-1600 in the secondaries.
