'95, MS2, gt2554 intercooled
So I'm perfectly happy at 8psi but I know I'm at the upper limit of my stock '95 injectors (265cc)
I was going to pick up some 305s or 460s just for peace of mind but I wanted to ask if I needed to change anything in MS. I don't plan on upping boost..
I'm at 11-11.5 at full load but I know my injectors are going full blast anytime I step on the gas.. should I even bother?

I changed from460 to the yellow top rx8 injectors I think they r 410cc and ev6 so a newer design with 4 squirts holes instead of 1 on ev1 460cc injectors.
Idle is much more stable afr.
Found them pretty cheap and retuning was not near as much as ev14 which is a huge switch. Req fuel will have to be changed for the larger injectors.
I have some flow force 610 on shelf I have not installed for fear of not being able to tune them.

I'll also figure out what I need to change to work with them.
I'm not scared of tuning and I'm trying to do my homework.. I just always get hung up on an acronym or concept I don't understand, so I have to stop and figure out what that is.. and I have trouble figuring out how each factor affects everything else in the tune. I think I have a tendency to overthink things when I should just say "ok" and move on.. I also have a pretty terrible attention span on top of that so I do struggle a little bit. There is also nobody else around here running MS I don't have any direct contact with someone that knows what they're doing.. so I do appreciate the replies.
